UV test chamber BS-04: Precise and flexible UV irradiation for material testing

The UV test chamber BS-04 is large, robust equipment for the time- or dose-controlled irradiation of samples with UV light. The chamber can be fully equipped for one of the spectral regions UV-C, UV-B, or UV-A to achieve the highest irradiance. Alternately, the use of two separately controlled lamp groups for different spectral regions allows for especially flexible operation of the chamber.

The interior irradiation chamber has a base area of 86 x 65 cm² and a height of 32 cm. The sliding sample carrier facilitates loading and unloading. With a load of up to 20 kg, this can withstand all demands. The sample chamber operating temperature is about 25°C so that thermal damage to the specimen is avoided. Due to the high uniformity of the irradiation, the samples may be positioned in any order.

The BS-04 can be equipped with two irradiation controls: the UV-MAT and the UV-MAT Touch. Both controllers regulate two spectral ranges independently of each other and ensure a constant dose despite lamp ageing, contamination or temperature changes. Calibrated sensors measure the dose precisely as they contain an accurate analog-to-digital converter and an integrated temperature sensor.

The UV-MAT Touch is operated via a high-resolution capacitive touchscreen. A powerful Cortex ARM processor ensures longevity and enables on-site updates. The device and the PC software are compatible with Windows 10/11. The display of numerical and graphical single and multi-channel irradiations, oscillograms and settings is clearly laid out. Parameterization is intuitive and password-protected directly on the UV-MAT Touch.

The optional PC control of the UV-MAT Touch enables multi-stage irradiation and comprehensive irradiation documentation.
