The MS-802 Secondary standard pyranometer is a 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.

The MS-802 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. 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 ...

Applications and uses

Conducting reliable and accurate solar radiation measurements needs some knowledge and attention: think of environmental influences (wind, rain/snow, soling), re-calibration (bi-annually), not to mention data processing, spectral effects, etc ...
