The MS-402 Pyranometer is a unique ISO First class pyranometer and best in its category. As the only first class sensor available on the market it has a built in electronic passive temperature compensating to linearize the detector temperature coefficient and make it accurate under all temperature conditions.

The two high-quality glass domes protect the detector efficiently from any thermal effects. The MS-402 is the only temperature-compensated First Class pyranometer on the market.

The design of the MS-402 First Class Pyranometer is very similar to the Secondary standard MS-802. Its robust brass mechanical construction makes it a durable sensor suitable to be used in harsh environments for routine global irradiance measurements. The MS-402 can be applied as multi purpose high …
