MS-40 Class C Pyranometer
ISO 9060:2018 Class C pyranometer for agro-meteorological networks and small PV sites, with analog output and certified calibration.
Key Features:
■ Spectrally flat
■ Analog output
■ ISO 17025 certified calibration
■ 5 year warranty
■ Optional MV-01 Ventilator & Heater
Description
The MS-40 is an ISO 9060:2018 Class C pyranometer based on EKO's universal sensor platform. It is the most cost-effective option for measuring solar irradiance across the entire solar spectrum and is designed for agro-meteorological networks and professional small-scale PV sites.
It features an analog mV output and is compatible with the optional MV-01 ventilator and heater as well as the albedo mounting kit. EKO manufactures this sensor under strict quality controls and provides a unique calibration compliant with ISO 17025 and IEC 9847 international standards.
The instrument includes a 5-year warranty, a recommended recalibration interval of two years, and no requirement to change the desiccant, simplifying field maintenance.
