CM3 Kipp & Zonen Pyranometer

Item Number: 162
Price: US$ 1,054.00

Model CM3

The CM3 is a rugged pyranometer manufactured by Kipp & Zonen. It is fully compliant with all ISO-9060 second class pyranometer performance specification criteria. The CM3 measures solar radiation with a high- quality blackened thermopile protected by a dome. The blackened thermopile provides a flat spectral response for the full solar spectrum range, which allows the CM3 to be used under plant canopies or lamps, when the sky is cloudy, and for reflected radiation measurements. The CM3 produces a millivolt signal that is measured directly by a Campbell Scientific datalogger.


To ensure accurate measurements, the CM3 should be leveled using a 14282 leveling fixture which incorporates a bubble level and three adjusting screws. The 14282 leveling fixture mounts to a tripod or tower using the CM225 mount. For most applications, Campbell Scientific recommends attaching a CM225 to a CM202, CM204, or CM206 crossarm. The CM225 can also be attached to a tripod or tower mast.
