PYR20 Solar Radiation/Pyranometer Sensor

PYR20 pyranometer, or solar Radiation Sensor, measures global radiation of both direct and diffusion of solar irradiance. The internal temperature compensation minimizing the error caused by heating of the sensor. Each sensor is calibrated against Eppley Precision Spectral Pyranometer and offers excellent accuracy and consistency. The sensor is applicable for science research, solar power , greenhouse, weather station etc.
