Measures solar radiation for evapotranspiration (ET) and Temperature/Humidity/Sun/Wind (THSW) Index.
Precision pyranometer
Detects solar radiation at wavelengths of 300 to 1100 nanometers. Solar radiation data is required (along with an anemometer and a temperature/humidity sensor) enables the weather station to report ET and THSW Index.
Designed for accuracy
Diffuser element and housing are carefully designed for accurate cosine response.
Silicon photo diode provides good match to solar spectrum.
Stands up to the weather
Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust.
