The ISO First Class MS-57 is a direct normal incidence (DNI) solar irradiance sensor. Also known as a pyrheliometer, it is used as a reference sensor for routine opera-tion on a Solar Tracker. The all-weather MS-57 is sensitive to solar irradiance in the spectral range 200 – 4000nm and works under the most extreme conditions in a temperature range from -40°C...+80°C.
