PESSL INSTRUMENTS PYRANOMETER

The IM506D Pyranometer is designed for field measurements of global solar radiation in agricultural, meteorological and solar energy studies. In clear, unobstructed daylight, the Pessl Instruments pyranometer has favourable results compared to the first class thermopile-type pyranometers, but is priced at just a fraction of the cost.
