The CMP3 is a rugged pyranometer manufactured by Kipp & Zonen. It 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. This allows the CMP3 to be used under plant canopies or lamps, when the sky is cloudy, and for reflected radiation measurements.
Measures natural sunlight, most types of artificial light, and reflected solar radiation (when inverted)
Measurement waveband: 310 to 2800 nm
Provides a flat spectral response for the full solar spectrum range allowing use under plant canopies or lamps, cloudy conditions, or for reflected radiation measurements
