UVA logger sensor NUL-232

UVA logger sensor NUL-232

There are different wavelengths of ultra violet light. The UVA wavelength range is 315-400 nm, which is 98% of the total UV radiation. The UVA radiation affects photoaging and also photochemical smog. The intensity of this light is measured in mW/m2 (milliwatt per square meter).

  • Used in the fields of Environmental Science, Biology, Physiology, Chemistry, Weather Science, etc.
  • Uses a special photodiode which reacts with electromagnetic radiation in the UV spectrum. An internal selective filter limits the range down to specifically the UVA range (315 to 400 nm) so only the UVA rays may pass through.
  • The sensor is pre-calibrated at the factory.
  • Experiment duration: 1 second to 31 days.
