100-6450 Solar Radiation Sensor with 3′ (0.9m) cable
Measures solar radiation for evapotranspiration (ET) and Temperature/Humidity/Sun/Wind (THSW) Index calculations.
The 100-6450 Solar Radiation Sensor measures global radiation, which is the sum of both the direct and diffuse components of solar irradiance at the point of measurement. The sensor is a silicon photodiode with a wide spectral response. The output of the sensor is a voltage proportional to the irradiance. Each sensor is calibrated against a secondary standard which is calibrated periodically against an Eppley Precision Spectral Pyranometer in natural daylight.
