Ultra-fast and incredibly accurate, with competition-beating long-term stability and exceptional reliability; the ISO 9060:2018 Class A MS-57 Pyrheliometer (MTI.AWS.EK.57) is a unique, second-to-none, direct normal incidence (DNI) solar irradiance sensor fully traceable to the World Radiometric Reference.
Designed for solar energy research, monitoring, and meteorological applications and built to weather extreme conditions, the MS-57 features an operating temperature range from -40 to +80°C and comes with an integrated low power heater to prevent dew and frost deposition on the outside window.
Made in Japan, our design and commitment to quality ensure that the MS-57 is best in class, and for every application.
