Precise VUV Measurement for 185 nm
- Reliable Sensor Technology for Laboratory Use

Vacuum ultraviolet radiation (VUV) at 185 nm plays a crucial role in water treatment, ozone production and air purification. Low-pressure mercury lamps that emit in this wavelength range are being specifically investigated for various applications:

Water treatment and pollutant degradation:
VUV radiation at 185 nm breaks down water constituents at a molecular level and contributes to the degradation of organic and inorganic contaminants. It also has a direct disinfecting effect.

Ozone generation and VUV/O₃ process:
VUV radiation converts oxygen into ozone, which is used as a powerful oxidizing agent in water treatment. In combination with VUV irradiation, the VUV/O₃ process significantly increases the degradation efficiency of pollutants and microorganisms.

Air treatment and pollutant degradation:
UV light in the wavelength range of 185 nm is also used for effective air purification. It specifically helps to break down:

• Odors (e.g. in food processing, sewage treatment plants, animal stables)

• Greases (e.g. from exhaust air streams in commercial kitchens and industrial plants)

• Solvents or VOCs (volatile organic compounds from paint shops, printing plants and chemical processes)

• Chemicals (tri, per, ammonia and other harmful substances)

The high-energy VUV radiation breaks down and oxidizes molecular structures so that pollutants can be efficiently reduced or completely removed. This makes a significant contribution to improving air quality and reducing harmful emissions.

Our VUV sensor is specifically designed for laboratory use and provides accurate measurement of 185 nm radiation. It provides reliable data for analysis and optimization of VUV processes and supports research in this challenging field.
