Product Introduction

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.

The MS-602 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025/9847.

Product Features

  • ISO 9060 Second Class Pyranometer
  • Most economic thermopile sensor
  • Compact all weather sensor
  • ISO 17025 certified calibration
  • 5 years warranty
