First Class Pyranometer
The 16131.5 series pyranometers are high-precision digital solar radiation sensors that meet the requirements of "First Class" according to the WMO guidelines and "Spectrally Flat Class B" according to ISO 9060:2018.
Model 00.16131.501030 is equipped with an on-board heater and thus meets the requirements for Class B PV monitoring systems in accordance with IEC 61724-1:2017.
The 16131.5 measures the solar radiation received by a flat surface in W/m2 from a viewing angle of 180°. Various digital and analog outputs are available for easy integration.
- Highest measurement accuracy in the "First Class" category
- Improved response time
- With integrated heating, version 00.16131.501030 meets the requirements of IEC 61724-1 Class B.
