The MS-80 set new industry standards on launch in 2016 and remains a class-leader for ISO 9060:2018 Class A solar sensors today, one of the few Class A pyranometers before the MS-80S and MS-80SH, in the top tier ‘fast-response’ and ‘spectrally flat’ sub-categories, with unprecedented low-zero-offset behaviour, and a 5-year recalibration interval.

The MS-80S built on that achievement with the addition of Modbus 485 RTU and SDI-12 digital outputs for improved compatibility with data loggers and SCADA systems; also introducing new internal diagnostic systems, now standard to all S-Series sensors, offering visibility over internal temperature, humidity, tilt, and roll angle; helping to ensure optimum performance without the need for regular physical checks.

These features, along with EKO’s unique 5-year recalibration …

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, …
