Saturday, June 11 the MECSPE fair in Bologna ended and we are truly grateful to all those who came out to see us.

It gave us the opportunity to display a selection of our measuring instruments and to discuss various measuring needs in person, without technological barriers.

This is the aspect we like most,  meeting our loyal customers directly and creating new ones.

We listen to what the company produces, what results it would like to achieve, or what problems need to be resolved.

SAMA Tools name-brand measuring instruments were created to cater these needs, but we also think that the assistance our technicians are able to provide pre-purchase can really make the difference.

What animates our company are certainly the people who, if you came to the fair, you will have met, albeit partially, because others remained at our headquarters in Viareggio.

Measuring instruments at MECSPE

For the 2022 edition of MECSPE, we selected various types of tools, suitable to satisfy the needs of manufacturing companies in various sectors.

Automotive, Oil & Gas, Naval, Food, Industrial Painting, Molds etc.

Force Measure

The measure of force encloses all tests essential for the quality and resistance of a specific product.

The main force tests include:




SAHSV-P(2021)Strumenti per misurare la forza di torsioneStrumenti per misurare la forza


These measuring instruments can be found in the section “Force measure”.

Measuring of the hardness of materials

When measuring the hardness of materials, we rely on portable or bench hardness testers.

There are different types of portable hardness testers, depending on the type of material or test to be carried out. They are mainly used to assess the hardness of the material for quality control in the production line and for the maintenance of structures and parts which are subject to wear.

strumenti per misurare la durezza dei rivestimenti strumenti per misurare la durezza dei materiali SAP180


These measuring instruments can be found in the section “Measuring the hardness of materials”.

Ultrasonic thickness measurement

To measure the thickness of a specific piece, the ultrasound technique is particularly recommended, as it allows you to measure a detail by simply placing the probe on it, without the need of any feedback from the opposite side.

In this case, the measuring instruments are the thickness gauges, which determine the thickness of a material by accurately calculating the time required by an ultrasonic pulse generated by the probe to pass through the thickness of the sample, which is reflected on the opposite surface and then returned to the probe.

Ultrasonic thickness gauges are ideal in the production phase, quality control, input control, PED inspections, material approval, output control and in all non-destructive tests where it is not possible to access both sides of measurement.

New Product! Fiberglass thickness gauge


In the photo: Fiberglass ultrasonic thickness gauge – SAUT6100D-SW


This new model, as seen in the photo, was first presented at MECSPE.  It is a graphic ultrasonic thickness gauge for fiberglass and composite materials. If you were present at one of our demonstrations at the fair, you will have seen how easy it is to use and its great potential for various fields, like boating, automotive, Oil & Gas, etc.

To verify that this tool is suitable for every specific need, S.A.M.A. can carry out tests directly on samples provided by our customers or alternatively, our technicians can personally go to shipyards or other establishments and carry out tests on site.  Other thickness gauges can be found in the sections:

Coating thickness measurement



Pendulum hardness tester SA509

Another instrument that aroused great interest and curiosity at the fair was the Pendulum hardness tester.  It is suitable for measuring the surface hardness of paints and coatings.

The procedure involves putting the gauge in contact with the surface coating which is then made to oscillate. Finally, the time required to decrease the amplitude of the oscillation at a certain value dictated by the standard under consideration is measured. The shorter the damping time, the lower the hardness.






In the photo:  Rotational abrasion tester – SAAB523


Another highly appreciated measuring instrument was the Rotational abrasion tester, mainly used to determine the abrasion resistance performance of various coatings by rotational rubbing, or to determine the abrasion resistance of paper, plastic, fabric, decorations, etc.

The samples are placed on the rotary plate and then subjected to the action of abrasion by two abrasive wheels with a determined pressure. The abrasive action is obtained by rotating the sample, while two abrasive wheels rotate above it. The wheels complete a full turn on the surface of the sample which allows to check the abrasion resistance at all possible angles of that sample.





Digital rotational viscometers - SAVISC152

In the photo:  Digital rotational viscometers – SAVISC152

The Digital rotational viscometer is ideal for testing the viscosity and resistance of a fluid.

The elegant model in the photo constantly controls the rotation speed and is widely utilized in chemical, medical, food, industrial, laboratory, scientific research fields, etc.

When an operator has to carry out the viscosity measurement in the laboratory, it is not always easy to identify the most suitable viscometer model. In these cases, our technicians are available to listen to each specific need and indicate the most appropriate solution.

This pre-sale consultancy service is free and allows us not only to concretely help our customers, but also to significantly reduce returns due to incorrect orders. Our philosophy is to always implement all preventive actions to avoid buying the wrong instrument.


Mechanical measuring instruments

The measuring instruments in our mechanical section are never lacking at the fairs we attend, since their use is extremely important and common in all manufacturing companies.

Mechanical measuring instruments can be found in the “Mechanical section”

Calibration of measuring instruments

At MECSPE, we also talked about our calibration services. Measuring and control instruments play a very important role within the production process of a company, such as guaranteeing the suitability of manufacturing products.

It is necessary that the instruments are efficient and remain within the tolerance range as dictated by the piece.  It is therefore essential to calibrate all instruments, even the simplest ones.

In this regard there are often many uncertainties, and our customers ask us questions like these:

  • What does ISO 9001 say in detail regarding calibration?
  • Why is it important to calibrate measuring instruments?
  • When should the calibration be repeated?
  • How long should the instrument be used before it is subjected to calibration and certification?
  • What if the certification does not go well or has errors?
  • What if the measuring instrument cannot be certified?
  • Do I need a calibration report or Accredia certificate?
  • What are the differences between calibration and Accredia certificates?

If you also have these kinds of questions, firstly, we recommend that you subscribe to our newsletter because in addition to providing you with useful information on the various types of measurements, it allows you to immediately receive an ebook on the ABCs of calibration via email.

how to achieve calibration without headaches

Instrument calibration is necessary and useful for many industrial sectors. Likewise, it is essential to have a solid intervention program to ensure minimal downtime.

The process of manufacturing efficient and high-performance industrial pumps  involves a series of inspections and tests, both before and after assembly.

These inspections and tests are helpful to verify that the manufacturing processes are carried out in accordance to fabrication criteria and required standards.

It is important to keep in mind that industrial pumps are normally exposed to many factors during operation. Some of those factors are:

  • Mechanical loads.
  • Hydraulic loads.
  • Thermal variations.
  • Environmental factors.

Therefore, the manufacturer needs to make sure the pump is ready to deal with all those factors which arise in the worst-case scenarios to guarantee they will operate efficiently and reliably.

Non-destructive testing for industrial pumps

Non-destructive testing is a great way to verify the pumps being manufactured are ready to operate efficiently and reliably.

Some common non-destructive tests applied on pumps include:

Ultrasonic tests

Ultrasonic tests are a great way to verify the performance of different areas of the pumps. Common areas tested with ultrasound technology include:

  • Material thickness
  • Material hardness
  • Material cracks and other discontinuities
  • Corrosion
  • Integrity of welds

It is clear that verifying the performance of the areas mentioned above is essential during and after the production of the pumps to guarantee proper operation.

This type of tests can be performed with tools such as:

Ultrasonic thickness gauges

Ultrasonic hardness testers

Ultrasonic flaw detectors

Magnetic particle detection

These types of tests can be performed by measuring instruments such as our ultrasonic thickness gauges, ultrasonic hardness testers or ultrasonic flaw detectors.

As the name suggests, this type of non-destructive test uses the magnetic particle method for the detection of possible flaws on the surface or at sub-surface levels of the materials.

This test is particularly useful to verify the integrity of welded areas and cast parts, with the possibility to identify cracks and other defects before the pump goes into operation.

Tools such as our AC/DC magnetic detector and our digital gaussmeter can be of great help when performing magnetic particle tests on pumps.

AC/DC magnetic detector and our digital gaussmeter

Dye penetrant test

This is a typical metallurgic test to verify the integrity of materials. It takes advantage of highly capillary liquids that are used to reveal possible defects and discontinuities on the material. This helps identify problems in welds, and other critical areas of the pumps.

Some penetrating liquids we offer include:

  • Fluorescent penetrant spray
  • White penetrating spray
  • Red penetrating spray

These are three important non-destructive tests that are recommended to guarantee that pumps are ready to withstand the factors mentioned above, especially those related to the operation of machines, such as mechanical and hydraulic loads.

Nevertheless, there is another important aspect to verify during and fabrication, and even after certain operational time, when maintenance is required.

Read on as we explain further.

Penetrant spray

Dealing with the environment

Pumps that are exposed to the environment, especially under tough conditions, require special protection to guarantee operation without failure.

A common practice is applying special coatings to protect against corrosion and other environmental effects. To achieve the required coating protection, both the surface of the materials being coated and the coating applied need to comply with certain requirements.

Some examples of these requirements are:

  • Adequate surface roughness
  • Proper adherence of the coating
  • Correct coating thickness
  • Expected coating elasticity
  • Specific hardness and abrasion resistance

To verify compliance with these requirements, some tests and measurements must be carried out. Tools that are necessary include:

In addition, pumps must be design to very tight tolerances and require high-precision manufacturing processes to operate at the highest possible efficiency. And those tolerances must be maintained throughout their lifespan. Moreover, thermal variations from operation or from exposure to the environment in different seasons may affect the dimensions of different parts, thus drifting away from the tolerance ranges.

A good way to ensure the parts of the pump are within the tolerance range, and identify whether thermal variations are having an impact is by performing dimensional verifications.

However, for some parts, dimensional verifications may require special measuring instruments. But any manufacturer striving for excellence knows the investment is worth it. And this is the case with several of our customers in this sector.

Other verifications to produce industrial pumps

There are also special measuring instruments that help the customers to guarantee the dimensions of different parts in pumps and pressure units comply with their standards.

Among the most chosen tools, there are the outside micrometers with exchangeable anvils and carbide tipped measuring faces reading 0,01mm – SAX101

With these instruments, you can measure even the biggest parts of pumps, including outside coverings while ensuring the tolerances are met to values as small as 0,01 mm.

Failure to comply with dimensional tolerances could result in reduced efficiency and/or reliability of products, which may bring different consequences such as:

  • Increased customer dissatisfaction
  • Reduced profitability
  • Loss of reputation

Fortunately, all those consequences can be avoided by implementing the right quality control (QC) and quality assurance (QA) processes while using the right tools.

Coating thickness measurement is an essential activity for many industries, which rely on the quality of their coatings and paintings.

These industries normally use coating thickness measurement as an accurate technique to verify that coatings applied on their products comply with their standards.

What is Coating Thickness Measurement?

As the name suggests, coating thickness measurement is a non-destructive testing method to measure the thickness of a coating applied on the surface of a product.

Apart from keeping the integrity of the part, an interesting aspect of this non-destructive measuring method is that it can be applied on both dry and wet coatings. The main difference between dry and wet coating thickness measurement will be the type of instrument employed.

Why is coating thickness measurement essential in many industries?

The fact that coating thickness measurement can be performed on both dry and wet coatings makes it a great solution for different industries and at different points of their production processes.

For example, quality control (QC) and maintenance departments can benefit from dry coating measurement tools to carry out inspections of dry insulating layers applied on metal substrate, such as paint and plastic layers.

These inspections are commonly performed to identify:

  •  Loss of coating layer that may result in corrosion.
  •  Incorrect coating thickness that may lead to premature failure of the coating.
  •  Coating thickness matches design requirements.
  •  Coating coming from suppliers matches order requirements (incoming goods inspection).

Timely detecting any problem on the coating can result in an increased lifespan of the coated part and a very significant reduction of costs in the long term.

Moreover, having the appropriate coating thickness allows achieving the desired balance between aesthetics and protection of the coated part. Thick coatings that are not even may result in undesired textures and the possibility of paint cracking leading to failure.

How to measure coating thickness?

As described before, there are two forms of measuring coating thickness: dry coating thickness measurement and wet coating thickness measurement.

Dry measurement is usually applied to measure any insulating layer applied on a metal substrate, such as paint and plastic layers. It is carried out by means of coating thickness gauges, such as our high accuracy digital coating thickness gauges which are capable of detecting insulating (enamel/paint etc.) and non-ferromagnetic (aluminum/zinc etc.) coatings over ferromagnetic substrates and insulating (enamel/ paint etc.) coatings over non-ferromagnetic substrates.

Coating thickness gauges use the magnetic induction measuring principle for ferrous base coatings and the eddy current measuring principle for non-ferrous base coatings. In addition to paint thicknesses measurement, these instruments can measure different types of coatings applied to sub-layers or resulting from galvanic baths such as anodizing, chrome plating, galvanizing, etc.

On the other hand, wet measurement is usually applied as part of the painting or coating application process, since it does not require the coating and varnish layer to be completely dry. This is especially useful for coating service providers, as it allows them to adjust immediately the coating layer as necessary without the need of post processing.

Common examples of wet coating thickness measuring instruments are our comb-shaped thickness gauges and rolling wheel wet film thickness gauges

What are the applications of coating thickness measurement?

As mentioned above, coating thickness measurement is essential for many industries.

Some of the sectors that commonly perform coating thickness measurement include, but are not limited to:

  •  Automotive.
  •  Aerospace.
  •  Marine sector.
  •  Commercial vessels.
  •  Mega yachts sector.
  •  Oil & Gas.
  •  Chemicals.
  •  Construction.
  •  Electronics.

Thickness gause fiels of application

Common activities in these sectors that require coating thickness measurement are:

Piping inspections in the oil and gas, and the chemicals sectors to avoid corrosion issues that may result in pipe failure, costly shutdowns and industrial accidents.

Checking the paint coating consistency on an aircraft or component in the aerospace industry for improved safety and performance.

Nautical and maritime maintenance, like in the case of bulkheads, tanks, ship hulls, and other coated components.

 Verifying the integrity of pressurized containers such as fire extinguishers, gas tanks, industrial boilers and others that depend on coatings for corrosion protection.

Maintenance inspections on bridges, especially those with metal structures, which are coated to withstand the hardest environmental conditions.


How to select a coating thickness measurement instrument?

Selecting the right coating thickness measuring instrument for your specific application is very important, since making a wrong selection may result in a total inability to obtain any value or obtaining false information.

Any of the aspects mentioned above means undesired consequences such as increased costs, customer dissatisfaction and loss of reputation.

To avoid all those problems, some aspects must be considered to select the right coating thickness measurement for your application:

  •  The coating type, whether it is dry or wet.
  •  The type of coating and material coated.
  •  The roughness of the coating. This also affects the type of probe to be used.
  •  The area measured and its location.
  •  The geometry of the part under test.


  • Coating thickness gauges

    Coating thickness gauges – SAWF, SAPIG548, SAWFR

At this point, it is also important to highlight that there are destructive methods to measure coating thickness. For example, our paint inspection gauge (P.I.G.) – SAPIG548 provides high accuracy measurements in the range of 2-2800µm on every substrate, like steel, non-ferrous metal, plastics, wood, concrete, plaster, among others with the aid of a built-in microscope allows you to measure the thickness of each layer. This instrument, thanks to its microscope, allows measuring both the total thickness of the coating and each single layer deposited on the substrate.

However, the integrity of the part is not kept, as this is a destructive test.

The fact is that, no matter your application, we have a coating thickness measuring instrument to cover your needs.

Of course, if you are not sure yet or have any doubts about measuring coating thickness, our recommendation is to contact us and one of our experts will gladly help you.


Ultrasonic thickness measurement or simply UTM is essential in many industries, especially those where the materials are exposed to harsh environmental conditions that may lead to wear and damage due to corrosion and erosion.

What is ultrasonic thickness measurement?

Ultrasonic measurement is a common non-destructive technique used to measure the thickness of a part in detail.

This means that the integrity of the part is not affected in the process. Another important aspect is that it is possible to obtain results by measuring only one side with the help of a probe. In other words, it is not necessary to complicate the measuring process like having to go inside a metal vessel.   Measuring from the outside will do.

Why is ultrasonic thickness measurement essential in many industries?

Ultrasonic thickness measurement can be applied to many different components and structures, and it provides a simple way to detect different problems. Some of the most common ones include:

  • Material loss due to corrosion and erosion.
  • Structural and welding problems on ships hulls and other components.
  • Damage resulting from splitting materials.
  • Defects on the surface finish of a finished product.

It is also a great way to control the quality of metal sheets and coated materials, which can be useful for manufacturers to validate the products received from their suppliers.


Ultrasonic thickness measurement SA8812

How to measure ultrasonic thickness?

The instrument used to measure thickness with this technique is commonly called an ultrasonic thickness gauge.

Operating an ultrasonic gauge consists of accurately measuring the time it takes for an ultrasound pulse generated by an ultrasonic transducer, known as the probe, to pass through the thickness of the sample, which gets reflected on the opposite surface, and finally returns to the probe.

After the time is measured the ultrasonic thickness gauge performs the calculation of the thickness of the material and displays the result on the digital screen, integrated within the instrument.

The calculation is performed by means of the following mathematical expression:

T = (V) x (t/2)
T = the thickness measured
V = the velocity of sound in the test material
t = the measured time

At this point, it is important to highlight that the velocity of the sound waves significantly varies from one material to the other, so it is important to calibrate the ultrasonic thickness gauge for the material being measured.

Fortunately, modern instruments like our Precision Ultrasonic Thickness Gauge – SAUT160 and Ultrasonic Thickness Gauge – SA8812 make this calibration very easy and able to measure the thickness on a wide range of materials such as:

  • Steel
  • Cast iron
  • Aluminum
  • Copper
  • Brass
  • Zinc
  • Quartz glass
  • Polyethylene
  • PVC
  • Gray cast iron
  • Spheroidal iron

Another important aspect of how ultrasonic thickness measurement is performed is the fact that some instruments require the material to be free of any coating, painting and residues such as rust caused by corrosion. This makes measuring thickness difficult in certain situations.

However, for these types of applications where the material in question has an existing coating, we offer the Through Coating Ultrasonic Thickness Gauge – SAUT310D-SW and the Graphic Ultrasonic Thickness Gauge – SAUT500D-SW:   two ultrasonic gauges that are capable to measure sample thickness excluding the coating over metallic substrates.

Ultrasonic thickness measurement SAUT160

What are the applications of ultrasonic thickness measurement?

As described above, ultrasonic thickness measurement is essential in many industries. Some of the sectors that commonly perform ultrasonic thickness measurement include, but are not limited to:

  • Oil and gas
  • Energy generation
  • Structural contractors
  • Foundries
  • Aerospace
  • Pharmaceutical
  • Food processing

Ultrasonic thickness measurement is generally used for quality control activities and maintenance inspections to detect corrosion on the workpiece.

Nevertheless, more specific applications are:

  • Wall thickness loss detection on piping, which require on-line and in-operation ultrasonic measurement. Different types of corrosion, and erosion due to flowing liquids and air bubbles can cause this material loss that may result in pipe failure, costly shutdowns and industrial accidents.
  • Nautical and maritime maintenance, like in the case of bulkheads, tanks, ship hulls, etc. The ultrasonic gauges capable of measuring through coating mentioned above are particularly useful for this application.  A specific thickness gauge model which is suitable for measuring materials such as fiberglass is the Fiberglass Ultrasonic Thickness Gauge.

Fiberglass is widely used in the boat manufacturing industry for recreational and work crafts.


Ultrasonic thickness gauge naval field

Graphic ultrasonic thickness gauge

  • The pressurized containers field, including fire extinguishers, gas tanks, industrial boilers and others. Again, the ultrasonic gauges capable of measuring through coating mentioned above are particularly useful for this application.
  • Lighting columns, also known as poles, are often exposed to harsh environmental conditions, water splashes from cars passing by and condensation on the swage joint. To avoid structural collapse, authorities are required to perform ultrasonic thickness measurements in a regular basis.
  • Tank trucks, especially those carrying toxic chemicals or flammable liquids such as gasoline, must go under regular inspections with ultrasonic thickness gauges since they are constantly subject to corrosion and erosion, and any structural damage may result in a terrible accident.
  • Maintenance inspections on bridges, especially those with metal structures which are exposed, in order the evaluate their structural strength.

How to select an ultrasonic thickness gauge?

Acquiring an ultrasonic thickness gauge should not be a challenge, and it only requires knowing the specific application required to make the right choice. Anyways, there are different aspects that require consideration when selecting the right ultrasonic thickness gauge.

The most relevant are:

  • The type of material or materials that will be inspected.
  • Whether inspections will take place on-line or in a quality control (QC) laboratory.
  • Whether through coating measurement is required or not.
  • The possible need for measuring samples with very small wall thickness values that require higher accuracy and higher resolutions.
  • The need for a graphic display and special functions for the highest professional levels.

No matter what the application, we have an ultrasonic thickness gauge for each of the aspects mentioned above. If you want to check the ultrasonic thickness measuring instruments we offer, just click here, or, if you prefer, you can contact us on Direct Industry.

However, if you are not yet sure or have any doubts about measuring thickness with an ultrasonic instrument, we recommend you contact us and one of our experts will gladly help you.

Are you looking for information on how to use an ultrasonic thickness gauge to measure the thickness of a given material, reliably?
Read on to understand how you can accurately use the gauge, just like our client, Project PSC does.

What is an ultrasonic thickness gauge?

An ultrasonic thickness gauge is an electronic device that uses the emission and reception of sound waves to measure the thickness of a given material.
It comes in different sizes and has various functions.
Each sector requires one type rather than another, therefore it is important to choose the most suitable model for each need.

probe thickness gauge

How does the ultrasonic thickness gauge work?

First,  you need to know what you have to measure. Each material has a different internal sound speed, which means that sound travels through different materials at different speeds.
This is an essential part of calculating the thickness of a material, because the thickness is equal to the echo cycle time divided by the sound speed.

To accurately calculate the thickness, the device must know the speed of the sound within the material it is measuring.

Since this is specific to the material itself, it is important to set the device for the material you want to measure.
Let’s look at some of the most common materials and associated internal sound speeds.


Material Speed (m / s)

Aluminium 3040 – 6420

Brick 3600 – 4200

Concrete 3200 – 3700

Copper 3560 – 3900

Glass 3950-5000

Iron 3850 – 5130

Lead 1160 – 1320

Steel 4880-5050

Wood 3300-5000


After setting it up, the device is ready to measure the sample accurately.

The second step is to determine whether the surface you need to obtain the thickness from is covered by some kind of coating.

What is meant by coating?

Thickness gauge kit

Coating means any material that covers the surface and prevents direct contact between the probe and the surface.

Examples of coatings are:

Hairspray, etc.

If you are using a Single Echo device (such as our SA8812 or SAUT160) the layers that cover the surface will cause a discrepancy with the measurements and will give you inaccurate results.

In this scenario, it is important to ensure that the surface is clean and that an insulating gel is used to form a direct connection between the probe and the surface. For devices that can use Echo-Echo and Multiple Echo methods (such as our SAUT310D-SW or SAUT500D-SW), coating is a minor problem and can be overcome.

Echo-Echo allows the ultrasonic thickness gauge to ignore a coating of up to 8 mm thick. The measurement process includes the device that produces an ultrasonic pulse, which is sent through the material you are measuring.

Timing begins when the pulse is initially emitted by the probe and ends when the return echo is detected, which reverberates through the material after bouncing off the bottom wall.

How do the different measurement methods work?

Single Echo is the simplest and, as the name suggests, uses a single timing method to measure thickness. This requires a clean sample of the material, which can be difficult to find in many areas outside controlled test environments.

Echo-Echo and Multiple Echo use two and three timers respectively to eliminate the thickness of the coating and obtain an accurate result for the sample thickness.
The second cycle of the sound wave begins at the boundary between the coating and the sample.
This is the key factor to remove the coating from the measurement, because it means that time one and time two will be slightly different.

Multiple Echo has a third timing to use, which increases measurement accuracy when the coating is thicker.
For this, times two and three are usually equal or infinitely different, so that the hardware and computing software can eliminate the coating and record only the thickness of the sample.

PROJECT PSC SRL also uses ultrasonic thickness gauge
