Product Description

The SRA20 albedometer is a sensor that measures global and reflected solar radiation and the solar albedo, or solar reflectance, with the highest accuracy. It consists of two SR20 secondary standard pyranometers with thermopile sensors; the upfacing one measuring global solar radiation, the downfacing one measuring reflected solar radiation. SRA20 complies with the latest ISO and WMO standards.
