MS-40 Second Class pyranometer is based on the EKO’s universal sensor platform with analog voltage output.
The MS-40 pyranometers have been designed for agro meteorological networks and professional small scale PV sites where solar radiation is taken seriously.
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 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.
