MS-40M Second Class pyranometer is based on the EKO's universal sensor platform with MODBUS RTU output. It is a cost effective solution for global solar radiation measurements. This sensor can be used in many meteorological networks and professional small scale PV sites where solar radiation is taken seriously. The MS-40M can be used with the optional MV-01 ventilator / heater.

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 is no longer necessary to change the desiccant.
