EKO’s new generation sensors broke the rules of traditional pyranometer architecture. 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 single dome, based on a 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-80M is a MS-80 with built in MODBUS RTU 485 converter, which is compatible to the industrial output standards. Due to the ultra-low temperature dependency and exceptional non-linearity ...

Applications and uses

Conducting reliable and accurate solar radiation measurements requires some knowledge and attention: think of environmental influences (wind, rain/snow, soling), re-calibration (bi-annually), not to mention data processing, spectral effects, etc ...
