MS-80A 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 compact sensor with a single dome, based on an isolated thermopile detector and Quartz diffusor is immune to offsets and integrates all optional value added functions such as a ventilator, heater and different industrial interfaces. The heater and ventilator are recommended, particularly over areas impacted by dew, frost, snow, and dust.

The MS-80A is a MS-80 with built in 4-20mA converter, which is compatible to industrial output standards. Due to the ultra-low temperature dependency and exceptional non-linearity characteristics, the converter ...

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 ...
