Campbell Sci – CMP6-L Solar Radiation

The CMP6 measures solar radiation with a high-quality blackened thermopile protected by two glass domes. Its flat spectral sensitivity, from 285 to 2800 nm, makes it ideal for applications in natural sunlight, under plant canopies, in green houses or buildings, and inverted to measure reflected solar radiation.

A desiccant-filled drying cartridge prevents dew from forming on the inner sides of the CMP6’s domes. Campbell Scientific also offers the CVF4 heater/ventilator that keeps its domes free from ice and dew.
