UV radiometers are used to determine the UVA, UVB, UVC and UVE spectrum.
A radiometer is a detector for measuring irradiance. However, the term radiometer is not only used for a functional principle. The light mill invented by William Crookes - an impeller that rotates when illuminated - does not measure the mechanical radiation pressure of the light, but is driven by thermal molecular motion. The inside of the glass bulb is largely evacuated. In special applications, only partial ranges of the solar spectrum are observed (e.g. the UV spectrum).UV radiometers are measuring instruments for measuring UV radiation. If UV sensors have the necessary calibration, several sensors can be connected to one display unit. The UV sensors are already integrated in the dose meters.
