The CS300 measures total sun and sky solar radiation using a silicon photocell. The spectral range of the sensor is 300 to 1000 nanometers, which encompasses most of the shortwave radiation that reaches the Earth's surface. The CS300 is designed for continuous outdoor use and provides solar radiation measurements for solar, agricultural, meteorological, and hydrological applications.
The "-L" on a product model indicates that the cable length is specified at the time of order.
