The MS-40S is an ISO 9060:2018 Class C pyranometer which is based on EKO's universal sensor platform. This sensor can be used in many meteorological networks and professional small scale PV sites where solar radiation is taken seriously.

The MS-40S with smart sensor technology and onboard diagnostic functions now standard for all smart sensors. Preserve the high accuracy of the sensor while complying with the various output standards used in the industry. The new Smart signal transducer which allows selecting from 4 types of output in one unit.  The new electronics ensure a great benefit for system integrators who work with various industrial interface standards.

The MS-40S with Smart transducer will also have additional features such as internal ...
