Controlling radiation from UV-C lamps is becoming more necessary nowadays. Current times have presented new challenges for the field of material storage and handling, since the pandemic requires constant sanitization. And this includes the use of technologies like UV-C lamps.

Lamps that emit UV-C light help disinfect different surfaces, water and even the air. However, this is only effective if the right amount of UV-C light is applied.

This said, it seems essential to find the way of controlling radiation from UV-C lamps in order to guarantee the disinfection process provides the expected results.

What are UV-C lamps?

UV-C stands for Ultra Violet C light. So, UV-C lamps are the type of lamps that work with Ultra Violet C light emission.

This type of light is in the range of wavelength that is invisible to the human eye, and it is one of the divisions of Ultra Violet light together with UV-A and UV-B.

According to the Foods and Drugs Administration (FDA) “UVC radiation has effectively been used for decades to reduce the spread of bacteria, such as tuberculosis. For this reason, UVC lamps are often called “germicidal” lamps.”

Clearly, UV-C lamps become a great tool for material storage and handling activities trying to guarantee a healthy and safe environment.

How is controlling radiation from UV-C lamps possible?

Like any other parameter control, controlling radiation from UV-C lamps requires some kind of measurement.

This means that anyone trying to control the amount of UV-C light applied to sanitize material storage environments and the materials themselves after handling activities requires measuring equipment.

Here is where the portable Delta Ohm Luxmeter becomes a great asset. Apart from being easy to carry and to operate, this instrument is capable of measuring:

  • Illumination
  • Luminance
  • Par
  • Irradiance.

Therefore, it is the perfect tool to accurately check the UV-C irradiance for disinfection equipment in a quick and efficient way.

And all these measurements will be supported by a instrument that is calibrated under ISO standards and on request provided with ACCREDIA certificate.

How would the wrong radiation levels from UV-C lamps may affect a company  and its customers?

As it was described above, not having the right amount of radiation would make sanitization ineffective. Also, the FDA describes that low doses of UV-C radiation may require a longer time to
effectively inactivate bacteria, which makes the process less efficient, thus reducing productivity for any company and its customers.

But efficiency and productivity are not the biggest of the problems. Not being effective to inactivate bacteria can carry health issues that can escalate beyond the companies as we have
already experienced.

In a more positive note, controlling the levels of radiation from UV-C lamps can help to:

  • Avoid bacteria and other sanity issues.
  • Reduce waste from discarded materials.
  • Reduced resources consumption from required extra sanitization runs.
  • Reduction of downtime related to contamination issues.
  • Obtain quality certified products.

Therefore, we can conclude that having the wrong radiation levels would make lose competitiveness and possibly their reputation, hence the importance of having accurate measuring tools.

What’s the luxmeter for in lighting systems?

Read on to find out and don’t miss the history of our customer Eurogroup S.p.A. that has managed to make more performing maintenance of such plants thanks to this tool.

What is the Luxmeter?

The luxmeter is a portable instrument used for the measurement of brightness, parameter involved in many areas such as environmental lighting, construction, road signs and advertising, safety clothing and horticultural sector, but not only.

It is used both for quality control and maintenance operations and this is well known by our customer Eurogroup S.p.A.


Who is Eurogroup S.p.A.?

Eurogroup S.p.A. operates in the design and construction of electrical and technological systems, telecommunications systems, data networks, security and automation.


The company, projected in the national and international panorama, boasts more than 250 employees and a share capital of € 2,500,000.00.


In 1966 the company was already very promising.
Born to offer a qualitatively competitive response in the field of electrical plant engineering, it already showed much wider development prospects.
The role now held has been conquered over time.
Thanks to a path of continuous growth, the company went from an artisan dimension to a broader, then projecting it into the national and international landscape and making it become, in 1996, Eurogroup S.p.A.
The company stands out for being constantly engaged in the development of innovative sectors such as Energy Efficiency, Renewable Energy and Building Automation.

Plants maintenance: service

Eurogroup s.p.A operates as part of the renovations and maintenance of plant with the Global Service and Facility Management services and guarantees a 24 hours a day and 7 days a week service.
It is precisely in the field of maintenance that S.A.M.A. Italia S.r.l. play a key role.

Measurement of brightness parameters of systems: the role of the luxmeter

For maintenance, it is essential to measure the brightness parameters of the systems.
Eurogroup S.p.A. has, in fact, purchased from us a luxury meter, with the aim of making their work in the field of public lighting more and more performing.
