The MS-802 Secondary Standard Pyranometer is the ultimate reference sensor to measure global solar irradiance with the highest precision. Its robust brass mechanical construction makes it a durable sensor suitable to be used in harsh environments. The MS-802 is used as standard for PV research and climatology studies around the world.
In combination with a Sun tracker (STR-series) or manual shading ring (RSR-01), respectively the Global Normal Incidence (GNI) and Diffuse (DHI) irradiance can be measured. The MS-802F is a MS-802 with integrated ventilator unit to improve the performance under various environmental conditions (prevents or minimizes the effect of dew, rain, snow, ice and dust).
