Instrument

CG 4
CG 4 Pyrgeometer

The CG 4 Pyrgeometer was designed for meteorological use to detect downward far-infrared (4.5 - 42 µm) radiation at the surface. The CG 4 is able to provide a voltage within its dome-shaped, 180 degree field of view that is proportional to the net radiation it measures in the far-infrared range that has a low sensitivity to temperature. Output from the instrument can be provided in under eight seconds.
