For exact determination of net radiation in short- and long-wave radiation range with two separately working receivers and with built-in Pt-100 resistance thermometer to determine reference temperature.
* "First class" according to WMO and ISO 9060 |
* world-wide market-leader |
* independent from ambient temperature |
* all-season measurements |
The measuring principle of the pyrradiometer is the measurement of the temperature difference between blackened receiver plates facing up and blackened receiver plates facing down by means of thermocouple elements.
The two receiver plates have two diferent output connectors.
Two drying cartridges keep the interior free from humidity.
Possibilities of measurement:
* Determination of net radiation
* Determination of radiation component
All instruments are supplied with a calibration certificate.
