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 will be minimized due to the cone shape geometry.
EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025/9847. The sensor has 2 years warranty with 2 years re-calibration interval are recommended
