The MS-40A is an ISO 9060:2018 Class C (Second Class) pyranometer which is based on EKO's universal sensor platform with Modbus 485 RTU output. This sensor can be used in many meteorological networks and professional small scale PV sites where solar radiation is taken seriously. 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-40M 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 by ISO/IEC17025/9847.

The sensor has a 5 years warranty with a 2 years re-calibration interval recommended and it ...
