The CMP pyranometer is an instrument for measuring the solar irradiance. The sensor measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The output is expressed in Watts per meter square andis intended for shortwave global solar radiation measurements in the spectral range from 300 to 2800 nm.

UVB Pyranometer is a  precision meteorological instruments for the measurement of biologically effective solar ultraviolet-B (UV-B) radiation The measurement technique employed utilizes colored glass filters and a highly stable UV-sensitive fluorescent phosphor to stop all of the sun's visible light and convert UV photons into visible light, which, in turn, is measured by a solid-state photodetector. It measures global solar irradiance, the radiation received by a horizontal surface from the entire hemisphere of the sky.
