Technical Description

The CS300 uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements for solar, agricultural, meteorological, and hydrological applications. Calibrated against a Kipp & Zonen CM21 thermopile pyranometer, the CS300 accurately measures sun plus sky radiation for the spectral range of 300 to 1100 nm. Sensors calibrated to this spectral range should not be used under vegetation or artificial lights.

The standard output is 0.2 mV per W m-2, which provides a signal of 200 mV in full sunlight (1000 W m-2). All of our dataloggers, including the CR200(X) series, can measure this output.
