Model PMA2140 Global Radiometer

Solar Light’s NIST-Traceable Model PMA2140 Digital Visible and Infrared Global Radiometer measures irradiance within the range of 400 to 1100nm, and is intended primarily for cost-sensitive applications where the flat spectral response of our thermopile-based pyranometers is not required. This sensor can be used to monitor the global solar irradiance (direct + diffuse.) It is factory calibrated to accurately read the global solar irradiance (from 300 to 2800nm) if exposed to the standard sun, even though the sensor is not sensitive beyond 1100nm. This is achieved by applying a correction factor during calibration. The angular response of the PMA2140 sensor is cosine corrected, and suitable for measurements of diffuse radiation or radiation from extended sources.
