The glossmeter is a tool used to measure the shine and gloss of surfaces. Before reading about why to choose the three-angle glossmeter for painted and polished surfaces, let’s see where it’s mainly used.

Where is the glossmeter used?

The glossmeter is employed in many sectors that work with painted and polished surfaces.  The main industries that use this device are:

  1. Automotive
  2. Furniture manufacturing 
  3. Metal polishing
  4. Industrial painting

In general, the glossmeter is used in any area where the surfaces must be high quality and meet specific standards of shine and gloss.

How does the glossmeter work?

The glossmeter releases a beam of light on the object’s outer surface and measures the intensity of the reflected light. Based on this principle, the glossmeter can determine the degree of gloss of the surface.  We’ve already written an article on the physical principles of the glossmeter, which you can read about.

There are several types of glossmeters, each of which is designed to obtain precise measurements based on the detection geometry and the degree of gloss of the surface. For example, some are equipped with three measuring angles, which allow accurate measurements regardless of the degree of gloss of the surface.

The SAMA Tools three-angle glossmeter is ideal for painted and polished surfaces

The SAGT526 high range tri-angle glossmeter by SAMA Tools is an indispensable tool for those who work in the painted and polished surfaces industries. Thanks to its three measuring angles, this glossmeter allows you to obtain precise and reliable measurements regardless of the degree of gloss of the surface.

As already mentioned,  this tool is designed to measure the gloss of a surface without damaging it, which makes it ideal for use in a wide range of industries. With an extended measuring range, automatic calibration and high accuracy, this instrument is one of the most professional available on the market.

One of the main advantages is its ability to provide reliable and reproducible results. This is particularly important in fields like the automotive industry, where vehicle surfaces must be high quality and meet the high shine and gloss standards set by car manufacturers.

Why should you calibrate your glossmeter?

The calibration of the glossmeter can be seen as a “snapshot” of the state in which the device is at that particular moment in time.  It provides information about the accuracy and reliability of the instrument, as well as revealing any problems or defects that could affect its ability to provide accurate results. Furthermore, it can be used as a reference to evaluate the evolution of the instrument over time and verify whether it is still able to provide reliable results.

Therefore, it’s important to calibrate the glossmeter because this important process allows one to check the operating status of the instrument and ensure its accuracy and reliability.

What are the risks associated with using an uncalibrated instrument?

Not performing periodic calibrations, may result in inaccurate readings that could affect business decisions or the quality of the finished product. Furthermore, calibration is important to ensure that the instrument always delivers accurate results, regardless of whether it hasn’t been used for a long period of time or if it’s been subjected to harsh environmental conditions.

Secondly, calibrating the glossmeter can help to identify any problems or defects that the instrument may have, which, once resolved by means of fine-tuning, allow to obtain reliable results again.

The Oil & Gas sector requires technologically advanced products, capable of operating in difficult environmental and climatic conditions. At the same time, when storing hazardous substances, preventive actions must be taken to reduce the risk of leaks. This certainly includes quality control procedures for Oil & Gas.

For example, tank corrosion can cause environmental contamination due to leaks. Based on this premise, each manufacturer must take care to inspect, service and calibrate their quality control equipment.

We are proud to be able to talk about one of our customers, who is a leading producer of welded pipes in the Oil & Gas market.

Quality control of welded tubes: Inox Tech Spa

Inox Tech S.p.A produces welded pipes (SAWL) in corrosion-resistant metal alloys (CRA). This Italian company, based in Lendinara was founded in 1989 and has evolved and specialized as a manufacturer and focuses on LNG, refineries and submarine applications with the highest quality standards, guaranteeing flexibility, reliability and effectiveness to all it’s customers.

Their main production line consists of thick welded tubes, with external diameters that can reach up to 110”, and with wall thicknesses of up to 70 mm. In addition to this particular line, they create solutions of smaller dimensions and thinner thicknesses, starting from an external diameter of 6”and wall thickness of 4 mm.

These pipes are mass-produced thanks to their recently renovated factory and first-rate technologies, which allows Inox Tech to reach a production capacity of 30,000 tons a year. The products obtained are only of the highest level, thanks to their API certification with the 3 monograms (API 5L, 5LC and 5LD), an ISO 9001 certified quality system, and various awards received from the most important companies in Oil & Gas such as: ExxonMobil, Shell, Total, and Saudi Aramco.

The internal laboratory guarantees high quality standards

In addition to the certifications mentioned above, the Inox Tech plant is equipped with a quality system and related equipment that allows them to check the characteristics of the materials, the quality of the welds, to ensure compliance with the regulations and above all, to guarantee the highest quality products.

It also collaborates with an independant accredited laboratory, which is located inside its own factory.  This allows them to perform the destructive tests on the materials required “in house” to verify the chemical and mechanical properties.

Destructive Control

The destructive tests that are usually required for their products include:

  • Product / Chemical analysis
  • Pull tests at hot and room temperature
  • Crease tests
  • Impact tests to -196 ° C
  • Hardness tests
  • Standard corrosion tests (G48, G28, etc.)
  • Drop Weight Tear tests (DWTT)
  • Hydrogen Induced Cracking tests (HIC)
  • Sulphide Stress Cracking tests (SSC)

Non-destructive Control NDT

While the non-destructive tests carried out entirely by their internal personnel include:

  • Penetrating liquids
  • Manual ultrasound tests
  • Radiography (traditional and digital X-rays)
  • Magnetic detectors
  • Positive Material Identification tests (PMI)

The stages of quality control at Inox Tech

We have already mentioned that Inox Tech is equipped with a certified quality system for all equipment and tools which therefore allows all quality control tests to be carried out internally.

Based on the test performed and what needs to be determined, quality control can be performed at every stage of the manufacturing process.

For example, if the goal is to determine the quality of raw materials, the test can be performed upon receiving the goods from suppliers. The welds can be verified as soon as they are completed, while the quality of the tube can be tested, as soon as it leaves the production line.

Having your own equipment and tools is a significant advantage, as it makes the company’s quality control system very efficient. Inox Tech also needs high-level quality control tools to make sure that all controls and inspections are accurate and reliable.

Although many people may think that achieving, the right color of a product is simple, in reality there is a sequence of very important of steps to follow in order to achieve the required color. We’ve already mentioned this in our recent article dedicated to our Romanian client, Benjamin Paints. Today we will see how to examine and check the color of molds and plastic components.

For an injection mold manufacturer, for example, finding defects in the color of an object represents a failure in quality control.  This results in the product being sold at a discounted price or even discarded, even before it is placed on the market.

That is why it is so important for the manufacturer to get the correct color.

Failure to achieve the correct color of a product before placing it on the market implies a wide range of issues that involve not only the economic aspect, but also puts the reputation and reliability of the brand at risk. Not to mention functionality issues:   for example when highly reflective colors that are required for certain applications, get unsatisfactory results.

Getting the colors right is essential, but how?

How can manufacturers check the color of molds and plastic components?

You may have already heard that colors are identified subjectively and emotionally. There is a lot of truth to this and precision work is at the base of it, by making sure that the color obtained is exactly the one specified.

Fortunately, technology has taken color measurement and control to the next level. While visual assessment is still the first step, there are tools like professional colour difference meters and color matching cabinets, that make color quality control much easier and more accurate.

But having state-of-the-art instruments isn’t the only step manufacturers need to take to get the right colors. Getting the best results involves a gradual process where every single detail has to be considered.

Here are some of the most important aspects that a manufacturer needs to achieve the best results:

Having a trained eye: visual inspection

As mentioned above, the first filter for color control is through visual inspection. When color differences are noticeable, having an expert eye that carries out this first inspection will save time and resources. However, when the differences become difficult for the eye to see, it is then necessary to use specific measuring instruments.

Using the right tools: colour difference meters and color matching cabinets

To check the color quality, the go-to instrument is the colour difference meter (see the article “Colour difference meter: what it is and why it is important”).

In some cases, a colorimeter is all you need.  However, there are some cases where tolerances require the highest level of accuracy possible or the nature of the product and the material used to manufacture it, require other types of instrumentation to be used. For example, a color matching cabinet can come in handy when a neutral environment with uniform light is required.

Color matching cabinet

How to use a colour difference meter and a color matching cabinet?

Having the best measuring instruments on the market is not enough, if you do not know how to use them correctly.

Having an expert eye for visual inspection coupled with training for correct instrument operation and correct interpretation of the results, makes a big difference in ensuring that the quality control process is 100% reliable.

Those who buy SAMA Tools name-brand measuring instruments will be guided step by step, via remote or in person, when they choose to combine our training courses with the purchase of an instrument.

On-site training courses for colour difference meters and color matching cabinets

Nowadays, many companies require training courses combined with the installation of the instruments/equipment, directly on-site, in order to fully understand how to use the tools effectively and straight away.

Our trained technicians explain how to use the colour difference meters in order to be able to compare the various components produced, with all the reference standards imposed by their customers, and thus identifying any delta deviations from the color values. This evaluation allows them to make all the necessary changes in order to ensure excellent quality while avoiding any kind of dispute.

However, many sectors work a lot with translucent objects, which is why it is imperative to have a color matching cabinet as well.

The cabinet allows you to recreate a neutral environment with uniform light, where the tested components are not affected by anything around them.

Thanks to our courses, the instrument features are explained in every detail, allowing for a better assessment of the differences between the various colors, mainly in transparent molds, which are hardly visible to the naked eye.

Our customers can thus ascertain whether the production is in line with the required standards, or not.

Training course

SAMA Tools colour difference meter and Color matching cabinet training course

After the training course, instrument adjustment and periodic calibration.

As human beings, we are not perfect. Even when well prepared, human error is present, so establishing clear procedures for how to take measurements is essential to minimize human error.

Furthermore, each certified company can guarantee higher quality thanks to specific procedures.

Not only people, but measuring instruments can also sometimes be wrong, which means that periodic calibration and adjustments should be included in these procedures.

Quality control in molding

Many S.A.M.A. Italia clients work in the field of molds and plastic components.  These are often activities within the automotive and household appliances sectors.

To fulfil their mission, they work hard to find accurate and reliable tools that can improve and optimize the work surrounding quality control.

Our customers carry out quality control inspections in order to understand how much the colors of their productions differ from the reference standards dictated by the orders they receive.

Maintaining quality certainly involves costs, but the lack of quality or more specifically, implementing procedures to eliminate complications and non-conformities, has a much higher cost.

Furthermore, non-conformities harm manufacturers because they cause a loss of customers, in the long run.

Therefore, we can say that compliance costs depend on how much has been spent to “do things well”, while those associated with non-conformities are the costs related to how much more has been spent for “not having done things well”.

So how much does quality really cost?

To clearly evaluate quality costs and to have a clear idea of one’s situation, it is essential to define and apply a quality measurement system.

The cost of quality can be placed into four categories:

  • Prevention Costs
  • Appraisal Costs
  • Internal Failure Costs
  • External Failure Costs

Compliance and non compliance elements

1. Prevention Costs in Industrial Quality Control:

Prevention costs are the expenses associated with all planned activities aimed at preventing the occurrence of poor quality/non-conformity in products or services.

Here are only some examples of prevention costs:

  • Training for workers involved in the service or delivery of the product
  • Definition of measurement methods with related procedures and checklists
  • Equipment inspection and the purchasing of the necessary measuring and control instruments
  • Tests on samples
  • Periodic reviews of projects
  • Selection of suppliers based on service standards and specifications for materials and services purchased externally
  • Quality system audits

2. Appraisal Costs for the Evaluation of Conformity to Quality Standards:

Appraisal costs are costs that are incurred to ensure the conformity to quality standards and performance requirements.

The examples of appraisal costs include:

  • Test and inspection (receiving, in-process and final)
  • Supplier acceptance sampling
  • Product Audits
  • Calibration

products quality control

3. Internal Costs for Production Failures and Deficiencies:

Internal Failure Costs are the costs that are associated with defects found before the customer receives the product or service.

The examples of internal failure costs include:

  • In-process scrap and rework
  • Troubleshooting and repairing
  • Design changes
  • Inventory required to support poor process yields and rejected lots
  • Re-inspection / retest of reworked items
  • Failure to carry out on-site (online) calibration which can lead to system malfunctions

4. External costs associated with post-sale Failures and Deficiencies:

External Failure Costs are the costs that are associated with defects found after the customer receives the product or service.

The examples of external failure costs include:

  • Sales returns due to defective products and their subsequent replacement
  • Service level agreement penalties
  • Complaint handling
  • Field service labour and parts costs incurred due to warranty obligations
  • Product recalls / Legal claims
  • Time lost due to resolution issues
  • Company reputation issues
  • Lost customers

non compliance replacement

Since 1994, S.A.M.A. Italia has been active in supporting companies and freelancers throughout the various stages associated with quality control.

Our know-how, which is built on our vast experience gained through precision mechanical workshops and by working with companies in various production sectors has allowed us to produce our SAMA Tools name-brand measuring instruments and to provide calibration service on all brands of instruments.

What sets us apart is the combination of our highly technical skills and the manner in which we attentively listen to our customers’ needs within the company.

By doing so, we can provide them with the right equipment to help better their production, while avoiding the problems described in point 4, regarding external failure costs.

After providing the most suitable measuring instruments, we take care of our customers by supporting them in the periodic calibration of their instruments.

But what if you own other non-SAMA instrument brands and need to calibrate them?

Those in possession of instruments of other brands can contact us without hesitation and ask for a calibration quote.  We offer both calibration reports referable to primary samples (RDT), and also ACCREDIA certificates.

This is an extremely important service that all companies that work with measuring instruments need!

It often happens that the same company needs to request an RDT for some instruments and an ACCREDIA certificate for others.

By contacting us, you can count on a single supplier, a very important aspect in terms of saving time, shipping and calibration costs, etc.

In fact, we at S.A.M.A. Italia personally carry out and issue the RDT laboratory test reports while carefully appointing the best accredited laboratories for the ACCREDIA certificates.

Calibration banner

Each laboratory is accredited for specific instruments so as a result, we are constantly evaluating the various accredited laboratories in order to always be sure who to send a particular instrument to.

Furthermore, based on the experience we have gained over the years, we believe that some laboratories are more thorough than others and are able to professionally and promptly respond to any post-calibration clarifications. This aspect should not be underestimated; on the contrary, it is extremely important!

This is why our customers’ instruments will only be sent to accredited laboratories that have passed our strict evaluations.

Just recently, a customer wrote to us, specifying that he absolutely did not want his instruments to be calibrated by certain laboratories, which coincidentally are not among those with which we work.

calibration certificate

Conclusion:  Compliance and Non-Compliance

Today, we have seen that being a quality-conscious company has its costs.  However, these costs will never be as high as those that arise due to poor quality.

The importance of quality vs. the costs of non-compliance

Quality control of the goods during the receiving, in-process/production and post-production phases, before placing the product on the market, is absolutely necessary.

To ensure that you purchase the right tools, our S.A.M.A. Italia technicians are available, even on-site, to evaluate your every need and offer you the best solutions for your measuring instruments.

The proper management of calibration intervals aims at safe and efficient production processes, which lead to quality products.

Although many companies consider calibration only as a means of obtaining a certification of legal value, calibration actually affects the overall effectiveness of the measuring instrument. This is, therefore, a very subtle point that can lead to non-compliant products and consequently serious problems and subsequent costs.

Making sure that the measuring instruments are functioning correctly, helps to prevent system failures.

It is important that companies understand what they need to do to reduce overall quality costs. This will help them improve business processes, which will ultimately lead to higher profits.

The worst type of costs to incur among these four categories are the ones related to external failures, whereby companies should do their best to try to reduce these types of costs.

For years, our company has been working hard to drastically reduce external failure costs.  We do so by checking each and every instrument, before it is packed and shipped out to our customers.

Quality assurance and strict monitoring by S.A.M.A. Italia

A careful inspection of everything we deliver obviously requires significant economic resources, but this is also what our customers have come to expect when turning to S.A.M.A. Italia for their instrument needs.

An almost 0% non-compliance average, translates into time saved and customers who in turn will receive no complaints from third parties.

It is therefore evident that spending more on prevention and appraisal costs usually leads to a reduction of internal and external failure costs.

A Force Gauge is a measuring instrument used in mechanics to evaluate an applied force. Read on because we are going to talk about the measurement of the weight force in traction and compression.

Moreover, thanks to G21 s.r.l. we will discover how this measuring instrument is used in a very particular sector, that of bone cements in orthopaedics.

What is traction?

Traction is the stress to which a body, subjected to a system of divergent forces, undergoes.

The principle of tensile breaking strength was discovered by Galileo Galilei and illustrated in the treatise “Discorsi e dimostrazioni matematiche intorno a due nuove scienze del 1638”.

What is compression?

In mechanics, compression is one of the elementary mechanical stress forces, together with traction and bending. Compression is the stress to which a body, subject to a system of convergent forces, undergoes.

Force Gauce for the measurement of weight force in traction and compression

SAMA Tools name-brand, digital force gauges with internal or external load, are widely employed to measure the force in tension and compression and are able to operate over a range of 200.000 N.

These measuring instruments offer sensitivity and precision, are ideal for the many needs and can be accompanied, on request, by a calibration report or ACCREDIA certification.


Force Gauges for bone cements

They are widely used in many industrial fields.

Today, we’d like to talk about the force gauge used for bone cements.

Bone cements are successfully employed to anchor hip, knee, shoulder and elbow prostheses.

The role of our customer G21 S.r.l.

G21 S.r.l is a company in Modena, Italy that creates innovative solutions in the field of biomaterials and procedures for vertebral consolidation and restoration of joint functionality.

Since 2010,  it has been opertaing according to a Quality System and conforms to EN ISO 13485 “Quality Management Systems – requirements for regulatory purposes applicable to Medical Devices”.

G21 has a catalogue of products (including long-term implantable and Class III medical devices) of which it has full know-how and design technology, and production.  Research and Development are conducted internally and in collaboration with important research institutions and universities at an international level.

The company focuses on high quality raw materials, absolute control of processes and suppliers and complies with the most stringent international quality standards.

G21 relies mainly on us for the supply and calibration of tools for the control of breaking loads.  Low traction forces in play require repeatability and high precision instrumentation, such as our Digital Force Gauges.

We’re talking in particular about the SADFGE-P model that is characterized by load cells of such sizes, that they cannot be integrated into the instrument body and sized to the loads they have to carry.

This tool uses a high-performance load cell that provides better accuracy, reducing bottom-up errors.

Get off to a good start with the SAMA Tools name-brand measuring instruments, just like G21 S.r.l. !

How is it possible to be sure that the same object does not present colour differences?
We discover it in this article, read on because today we talk about the main colour measurement instrument: the colour difference meter.
You will understand all its features and you can see it in action in the video we made for you.

What is a colour difference meter?

The colour difference meter is a device used to measure chromatic differences, which allows performing accurate measurements of differences between all colour types of the same material, according to the international standards.


[Video] Do you need a colour difference meter – color meter?


Objects’ colour

Design colour’s choice is extremely important, even if is quite subjective.

Colours arouse emotions and this particular emotion may differ from person to person.

Studying how colours influence people is a real kind of business.

The simple change of a tone or a saturation is enough to arouse completely different feels.

Moreover even cultural differences should be considered, because what means happiness somewhere, could means sadness in somewhere else.

Our Logo, for instance, RED and BLUE show different meanings between Orient and Occident.

• Occident: excitement, love, passion
• Orient: wedding dress, joy

• Occident (Europe): relaxation, confidence
• Orient: sadness, depression, wedding tradition, prudence

Colour perception

What is really important for any producer is to be able to reproduce the chosen colour without facing the risk of visual errors.

Light, object and observer are three essential components in colour perception.

The variation of one of these three components changes inevitably the colour perception.

In the event that light and observer do not change, the object will define the observer’s colour perception.

The object can influence colour perception because his reflective surfaces (transmittance surfaces) modulate the spectrum of the light source.

Each object has several reflectivity surfaces, these one are modified by the light source obtaining various results.

The same observer, but different colours perceived.

The colour difference meter help us to measure chromatic differences.



Calibration report for the colour difference meter

An optional service for the colour difference meter is the calibration report.

It is a document edited by metrological laboratories that insures that the test has been made with reference to national acknowledged samples.

The technical worthiness of these documents is based on the laboratory’s qualification, on the operator’s expertise and by the metrological procedures employed.


Application fields

Colour difference meters are able to operate on plastic, metal, printings and painted surfaces.

They are mainly employed to perform quality checks on incoming and outgoing goods.

How the colour difference meter works?

The colour difference meter operating principle is based on the measurement of chromatic aspects of the light that arrives on the surfaces from any source, directly or indirectly.

Suitable for intermediate stages analysis in producing materials such as:

  1. Clothes
  2. Building
  3. Interior design
  4. Plastics
  5. Paints
  6. Facings
  7. Porcelains



It is a perfect device to be used for field measurement.





It is used to check chromatic differences between samples of the same material in a fast and accurate way.

In this article we have the pleasure to talk about our collaboration with the company Ing. Ferrari S.p.A.: read on to find out how the company optimizes the calibration process of measuring instruments!

Who is Ing. Ferrari S.p.A.?

Ing. Ferrari S.p.A. is one of the major Italian companies in the design, construction and management of complex and technologically innovative works and systems.

  • Sizes

The company based in the province of Modena has seen steady growth over the past 5 years, up to a turnover of over 71,000,000 € and more than 230 employees.

  • History

Founded by Eng. Carlo Ferrari in 1917,  the company built at the time heating systems and electrical systems for civil use.
In the following years it moved towards an industrial and managerial target of high standing, such as the prestigious car manufacturers Ferrari, Lamborghini and Maserati, for which Ing. Ferrari S.p.A. realizes works of great importance from a technological point of view.

Since 2013 it has been operating as a General Contractor providing the customer with a single interface, from the project to the delivery of the finished work and its subsequent maintenance.
He takes care of the building in its completeness as regard the realization of construction works and technological systems.



Plant maintenance: service

Ing. Ferrari S.p.A. is very attentive to the service of plants maintenance operating 24 hours a day, which ensures the regular efficiency of the plants with a service program that provides, plans and manages maintenance optimizing their performance.

Calibration of measuring instruments: S.A.M.A. Italia’s role

Recently Ing. Ferrari stated on Linkedin that “it carries out a systematic activity of calibration of all the measuring instruments used for the maintenance activities at customers, even thanks to the collaboration with S.A.M.A. Italia Srl – SAMA Tools.”



It is a source of pride for us to be suppliers of the Emilian company since 2018.

They turned to S.A.M.A. Italia precisely because they needed to periodically check several measuring instruments aimed at the maintenance of industrial and civil plants.

We are talking about torque wrenches, manometric groups, oxygen detectors and other instrumentation related to the F-Gas sector.

Why did Ing. Ferrari choose S.A.M.A. Italia for the calibration of measuring instruments?

It is clear that a company that provides a 24-hour maintenance service must equip its technicians with dozens and dozens of measuring instruments.

Ing, Ferrari S.p.A. wanted to improve the previous management of the periodic calibration service, which before 2018 was to send the fleet of instruments, divided by type, to multiple suppliers.
This involved a huge amount of time to the staff of the purchasing office who had to deal with every time several companies and logistics, which had to prepare several pallets with different destinations.

Moreover, it was not always easy to talk to the technicians to ask for clarification on the certificates issued.

Ing. Ferrari S.p.A. absolutely needed to find a more efficient solution!



The purchasing office has therefore started a careful search among the various alternative suppliers, up to choose S.A.M.A. Italia.

It’s time to find out how Ing. Ferrari S.p.A. has come to optimize the calibration process of measuring instruments.

Why just us?

The factors that led to this choice were to be able to count on:

    • A single supplier for almost all the equipment stock and therefore a considerable saving of time and money in being able to employ staff to perform other tasks;
    • Speed in returning the calibrated instrumentation;
    • A set-up service, necessary on many instruments that pass directly from the hands of their technicians to the calibration laboratory;
    • Excellent quality/price ratio;
    • High technical preparation and availability in providing clarification on the certificates issued;
    • Customization of the service, adapting it to their needs.

In summary, we take care of managing every measuring instrument both from the point of view of periodic calibration and of any tuning, in order to guarantee to every technician of Ing. Ferrari S.p.A. a perfectly working instrument, in line with all the standarts required by the regulations.

That of S.A.M.A. Italia and Ing. Ferrari S.p.A. is a collaboration in continuous growth that has allowed us to give an added value to our service, adapting and customizing it to such a prestigious company of our beloved country.

Every satisfied customer is a source of great pride for us, but it is precisely when you are chosen by large companies with high standards, including Ing. Ferrari Sp.A., that we understand that we are on the right track.
