ISO Secondary Standard Pyranometer
MS-802/MS-802F

- MS-802 is the precision pyranometer for the global solar radiation measurement.
- MS-802 meets the performance criteria of the ISO(International Standard Organization) high class, formally called Secondary Standard, pyranometer.
- The solar radiation measurement is utilized for many thermal and photovoltaic solar energy applications.
- MS-802F is MS-802 with the ventilation system, which prevents the influence of frost, snow and dust.
