MS-80S is a "Spectrally flat" ISO 9060:2018 Class A pyranometer. The innovative patented design was inspired by the combination of latest technologies and state-of-the-art thermopile sensor, enabling a breakthrough in unprecedented low zero-offset behaviour and fast sensor response.

The MS-80S with smart sensor technology and onboard diagnostic functions is now standard for all EKO smart sensors. It preserves the high accuracy of the sensor while complying with the various output standards used in the industry. The new Smart signal transducer allows selecting from 4 types of output in one unit (MODBUS 485 RTU, SDI-12, 4-20mA, configurable 0-10mA / 0-1V with external optional 100Ω precision shunt resistor). The new electronics ensure a great benefit for system integrators ...

Applications and uses

The accurate solar radiation measurements and the reliable driving require a little knowledge and attention: think about environmental influences (wind, rain/snow, soiling), re-calibration (bi-annual), without mentioning data processing, spectral effects, ...
