SRA11 first class albedometer is an instrument that measures global and reflected solar radiation and the solar albedo, or solar reflectance. It is composed of two SR11 first class pyranometers, one sun screen, one glare screen and one fixture with rod. Mounting hardware and tools are included. Each pyranometer has a thermopile sensor and offers output in millivolt; the upfacing one measuring global solar radiation, the downfacing one measuring reflected solar radiation. SRA11 complies with the latest ISO and WMO standards. The modular design facilitates maintenance and calibration.
