Product Specification

MS-402?First Class Pyranometer?Description
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 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 quality monitoring sensor in the PV and Meteorological market. MS-402F is a MS-402 with 110VAC/12 VDC ventilation system to prevent any possible influence of frost, snow and dust.

MS-402?First Class Pyranometer?Features
? Most accurate first Class Pyranometer
? Reponse time (95% < 8s)
? Temperature compensated <1% (for 50°C band)
? Near Secondary standard specifications
