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
