The pyranometers in this series are all based on the thermopile principle, very accurate. 
This principle provides a µV signal without the need for an external power supply. To be able to transfer the signal over a longer distance and to prevent interference, most types are equipped with an integrated transmitter. 
When using a 4-20 mA, an external active power supply is necessary. The output of these series is always related to W/m2, making it possible to have a relation to the total solar panel surface.
All our pyranometers are made in a way that the electrical system is totally isolated from the housing, making it possible to mount the pyranometer on any surface, including metal ones, without the need of isolation.
Delta OHM is one of the main pyranometer producers worldwide. We produce a full range of pyranometers according to the ISO 9060: 2018 - Spectrally Flat Class A, B and C.
Each of our pyranometers is calibrated separately during production; all are supplied standard with a Report of Calibration in accordance with the ISO 9847:1992. Next to this, we are the only pyranometer producer that has invested in a full range of 6 accredited ISO 17025 Calibration Laboratories.
Pyranometers can be used as stand-alone or in combination with our weather stations. 


Includes 5m cable and shade disk. Pole and bracket are not included.
