SRA20 albedometer is an instrument that measures global and reflected solar radiation and the solar albedo, or solar reflectance, with the highest accuracy. It is composed 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.
- global solar radiation and reflected solar radiation
- albedo or solar reflectance
