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 for PV research and climate research, and by ogy in research worldwide. Combined with a solar tracker (STR series) or a manual shading ring (RSR-01), it is respectively for global normal incidence (GNI) and
