EKO MS-series pyranometers are very reliable. The MS-802 is used for the most demanding applications in PV, meteorology, field research and solar radiation monitoring of global, tilted and diffuse irradiance.
EKO MS-80 is a thermopile type pyranometer which has a 180 degree field-of-view for measuring the hemispheric solar radiation with a cosine-weighting function.
Depending on the model either one or two transparent glass domes protect the sensor efficiently from thermal effects.
All EKO pyranometers are IEC 17025 calibrated.
