Ultra-fast and incredibly accurate, with competition-beating long-term stability and exceptional reliability; the ISO 9060:2018 Class A MS-57SH Pyrheliometer (MTI.AWS.EK.57SH) 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-57SH 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-57SH is best in class, and for every application. The MS-57SH built on that achievement with the addition of Modbus 485 RTU and SDI-12 digital outputs for improved compatibility with data logger systems; also introducing new internal diagnostic sensors, now standard to all S-Series sensors, offering visibility over internal temperature, humidity, tilt angle; helping to ensure optimum performance without the need for regular physical checks.
These features, along with EKO’s unique 5-year recalibration interval, and new low power consumption integrated solid-state window heater make the MS-57SH the best value Class A sensors available; ideal for complex networks, hard to reach locations, and monitoring networks with restricted access.
