Decagon PYR Total Solar Radiation

Measure Total Solar Radiation

The PYR total solar radiation sensor (pyranometer) measures the solar radiation flux density (in watts per metre squared) from a field of view of 180 degrees.

Weatherproof for Long-Term Use

The sensor is completely water proof, submersible, and designed for continuous outdoor use.


Accurate measurement depends on cleanliness of the lens and installation at horizontal (180°). The sensor head has a domed diffusion disk to reduce the need for frequent cleaning. A levelling plate is included for accurate installation.
