Digital secondary standard albedometer
SRA20-D2 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-D2 secondary standard pyranometers and one AMF02 albedometer mounting kit. AMF02 includes one glare screen, one mounting fixture with rod, mounting hardware and tools. Each pyranometer offers two types of commonly used irradiance outputs: digital via Modbus RTU over RS-485 and analogue 4-20 mA (current loop). Individually tested for temperature and directional response, SRA20-D2 is the most accurate digital secondary standard albedometer available. SRA20-D2 complies with the latest ISO and WMO standards. The modular design facilitates maintenance and calibration.
