The MS-40 is an ISO 9060:2018 Class C pyranometer which is based on the EKO's universal sensor platform. It is the most cost effective irradiance sensor to measure Solar irradiance accross the full Solar spectrum. It can be used for agro meteorological networks and professional small scale PV sites where solar radiation is taken seriously. The MS-40A and MS-40M provide a digital output (4-20mA or Modbus 485 RTU). The MS-40/40A/40M can be used with the optional MV-01 ventilator / heater or can be combined with the optional mounting kit for albedo measurements.

The MS-40 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. EKO provides a unique calibration compliant to the international standards defined ...
