The solar radiation sensor is used to measure shortwave radiation reaching the Earth's surface. (Product does not include the Sensor Mount as shown in photo above).
The SP-series silicon cell pyranometers is calibrated to measure total shortwave radiation. This cosine-corrected sensor is designed to maintain its accuracy when radiation comes from low zenith angles.
