ML-01 Si-pyranometer complies to ISO 9060-2018 "Fast response class C" and is made for high quality irradiance measurements. The ML-01 is an industrial grade solar sensor specially made for  irradiance measurement applications for the meteorological, agricultural and environmental studies. The compact dimensions of the sensor body make it easy to integrate it within any application using it with or without a mounting plate. For global horizontal measurement applications, the sensor can be mounted in the horizontal position with a standard removable mounting plate with a spirit level and leveling feet. The Mono-Silicon detector with UV resistant diffuser gives a cosine response also at low solar elevation angles. Besides the effects of soiling or water deposition on top of the diffuser ...

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, ...
