Japan EKO Photoelectric Sensor
The MS-802 standard pyranometer is a reference sensor for measuring solar energy, featuring high-precision irradiance. Its robust brass mechanical structure makes it a durable sensor suitable for use in harsh environments. The MS-802 is used as a standard in PV research and climate research, and in research worldwide. When combined with a solar tracker (STR series) or a manual shading ring (RSR-01), it measures global normal incidence (GNI) and diffuse horizontal irradiance (DHI), respectively.
