The MS-40 Pyranometer (MTI.AWS.EK.40) is an ISO 9060:2018 Class C pyranometer based on EKO’s universal sensor platform. It is the most cost-effective irradiance sensor to measure Solar irradiance across the entire solar spectrum and is designed for agro-meteorological networks and professional small scale PV sites.
Featuring an analog (mV) output, every MS and S-Series Pyranometer, including the MS-40, is compatible with the optional MV-01 ventilator & heater and albedo mounting kit and is manufactured with strict quality controls and performance standards.
EKO provides a unique calibration compliant with the international standards defined by ISO 17025 and IEC 9847. The sensor also has a 5-year warranty with a two year recommended recalibration interval and no requirement to change the desiccant.
