The ISO First Class MS-56 measures direct normal incidence irradiance (DNI). Also known as a pyrheliometer and used as a reference sensor for routine operation on a Solar Tracker. The all-weather MS-56 is sensitive to solar irradiance in the spectral range from 200 – 4000nm and works under the most extreme conditions in a temperature range from -40°C -80°C. The versatile MS-56 combines all features of a quick broadband detector enabled by an advanced technology thermopile detector.

The integrated low power window heater prevents dew deposition or frost on the outside window. The MS-56 has a robust but compact and smooth design which forms the new generation of EKO Instruments solar radiometers that are designed for most demanding Photovoltaic ...

Applications and uses

Solar Direct Normal Irradiance (DNI) represents the direct solar component and contains about 80% of the total solar energy budget on earth. Outside the atmosphere (AM0) the solar irradiance is ...
