The new SUV series offers a measurement solution for every part of the ultraviolet solar radiation spectrum. The successful SUV5 total UV radiometer has been re-engineered into dedicated UVA, UVB and UVE (UV Index) models to make a range that is smarter than alternatives; thanks to the latest detector technology, digital signal processing and Modbus® output.

Ultraviolet (UV) radiation is part of the Sun's light spectrum that reaches the earth. UV radiation breaks down into wavelengths that are invisible to the naked eye. There are three types of UV rays: UVA, UVB and UVC. They decrease in length from A to C but increase in intensity, meaning that the shorter the wavelength, the more potential for damage. Fortunately, only UVA and UVB rays can penetrate the earth's atmosphere. With the new SUV-A and SUV-B you can measure both single wavelengths.

UVE light:

  • Limited amount reaches the earth's surface (mainly absorbed by atmosphere)
  • Is considered a risk factor for skin cancer
  • Corresponds with the sensitivity of the human skin
  • Is found in man-made sources of UVC radiation (mercury lamps, welding torches)
  • Is used in to calculate the UV-index
