Product Description

The MS-802 Pyranometer is a Secondary standard reliable reference sensor to measure global broad-band radiation with high precision. It is used as a standard in PV research and climatological studies around the world.

A high quality double-dome construction is adopted to improve the accuracy of the measurement and to minimize unwanted thermal offsets. The ventilation unit of the MS-802F model will reduce the deposition of dust, dew, frost, snow.

For each sensor the directional response and temperature dependency are measured and validated through a measurement report that comes with the sensor. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025/9847.
