A pyrgeometer is an instrument which measures far infrared atmospheric radiation (4.5 µm-100 µm).
Pyrgeometers are designed to operate in the field, even under the harshest climatological conditions. They are used in meteorological, atmospheric and other studies.
The pyregometer contains a thermopile which generates and output voltage when heated. This sensor sits beneath a silicon window which protects it from the environment and filters out all but the far infrared rays.

Pyrgeometer 4500 - 42000 nm, max. 15 W/m² | CGR 3 Kipp & Zonen
The CGR 3 is a pyrgeometer, designed for meteorological measurements of downward atmospheric long wave radiation. The CGR 3 provides a voltage that is proportional to the net radiation in the far infrared (FIR). By calculation, downward atmospheric long wave radiation is derived. For this reason CGR 3 embodies a temperature sensor. The CGR 3 uses a specially designed...
