7821 Solar Radiation Sensor, Standard

This product has been discontinued.

For use with standard versions of GroWeather, Energy EnviroMonitor, or Health EnviroMonitor.

Measures solar radiation. Also required (along with an anemometer and a temperature/humidity sensor) if you wish to monitor evapotranspiration.

Diffuser element and housing are carefully designed for accurate cosine response. Silicon photo diode provides good match to solar spectrum. Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust. Includes built-in level and 40' (12 m) standard cable.
