UV Radiometers

Sorry, this product cannot be purchased.

A UV meter is used when the effect of UV radiation on a biological or chemical process, or the negative or positive effect of UV radiation on human health, needs to be quantified and documented.

The requirements for UV measuring instruments result from individual customer-specific inputs or from a law, a standard, or a directive. Our measuring devices consist of a calibrated sensor, which is connected with a cable or via a radio link to a display device or a PC or data server. The display device is either produced by sglux or consists of a smartphone or server operated by the user. Our UV measuring devices with their motto: “Measure-Understand-Evaluate” occupy a top position worldwide in terms of their precision and user-friendliness. Since 2018, they are in sovereign use: most of the 27 stations operated by the Federal Office for Radiation Protection in Germany for recording the solar UV index are equipped with sglux sensors.

When selecting a suitable radiometer, as a first step, the use of the “SXL 55” universal radiometer is to consider. The smartphone-based device with its intuitive operating functions guarantees error-proof UV radiation measurements. The SXL 55 is suitable for the majority of common applications. For very special measurement requirements, other devices are available, which are presented in the list below after the SXL 55. All UV radiometers undergo a PTB traceable calibration before delivery.

When processing the customer’s inquiry, we first obtain an understanding of the customer’s measurement task. This information is used to select and configure the measuring instrument in terms of its dynamic range, spectral response characteristics, output signal, external geometry, calibration method as well as special requirements (regarding temperature, waterproofness, speed, dirt, power supply, etc.). Accordingly, our UV measuring devices can be used for every type and intensity of UV radiation (as well as UV+VIS, blue light, etc.) can be configured and calibrated.

The delivery time of our UV measuring instruments is a maximum of three weeks.

UV Radiometers FAQ

How much does a good UV radiometer cost?

UV radiometers are available on the internet for as little as about €50. However, we do not recommend buying these radiometers, as they usually do not provide any information about the calibration procedure and the spectral properties of the sensor. For hobby UV measurements or for a rough estimate of the UV irradiance during laboratory experiments, we recommend the measuring devices from the American manufacturer Solarmeter. These devices are based on an sglux SiC photodiode, are robust and come with calibration and spectral information. They are offered in various web shops for around EUR 200. The sglux UV radiometers cost about EUR 1,000. They are used in industrial applications or for scientific work where precise knowledge of the irradiance is relevant. In contrast to the Solarmeter products, our radiometers offer additional functions, such as dose measurement and a logging function. The sglux radiometers also have a field of view which is almost perfectly matched to the cosine function. This allows for a good reproducibility of the measurements and a good comparison with measurements taken at other locations. Another advantage of purchasing a sglux measurement device is that that we customize our devices in cooperation with the customer with regard to the dynamic range, the spectral properties and the PTB-traceable calibration, which is always included in the price. This is how we ensure the measurement success of our customers. The measurement devices from sglux are a bit less expensive than other devices on the market that are suitable for professional use. The reason for this is the display unit chosen by sglux, a smartphone. This eliminates the costs of an elaborate in-house production of the display unit. Sometimes a UV radiometer is not enough. This is always the case when knowledge of the total value (integral) of a radiation source does not provide sufficient information, but rather the spectrum of the source, resolved by wavelength, is to be determined. For this, a spectroradiometer is required. In our laboratories, we use the BTS spectrometers from Gigahertz Optik for this purpose, and we can recommend their purchase.

Which waterproof UV measuring device can I operate permanently outdoors?

sglux offers the UV transmitter, a solar-powered network node with a connection to the mobile phone network or the UVMicrolog data logger. Both devices can be equipped with different sensors and different calibrations.

Which device is suitable for a belt application (sterilization or curing line)?

sglux is specialized in in-line monitoring, i.e. the continuous monitoring of emitters using permanently installed sensors. By using the radiation-hard semiconductor material SiC, this is also possible at very high irradiation. If the design of the system does not permit in-line monitoring, the uvLink or the UVMicrolog can move across the conveyor belt.

Which devices are suitable for DVGW/ÖNORM-compliant measurement?

sglux offers the UVRRM reference radiometer, which is approved for many years. If more than one or special calibrations are required (e.g. LED), the UV Radiometer SXL 55 or the UVTOUCH should be used.
