Within the MS-series the MS-602 pyranometer is the smallest true thermopile pyranometer. It is the most economic measurement solution for global solar radiation measurements capturing the full solar spectrum. MS-602 meets the ISO Second Class performance criteria.  However, its outstanding temperature dependency characteristics can only be found on higher class pyranometers. This sensor can be found in many meteorological networks and professional small scale PV sites where solar radiation is taken seriously.
