How to choose this product


A pyrgeometer is an instrument which measures far infrared atmospheric radiation (4.5 µm-100 µm).


Pyrgeometers are designed to operate in the field, even under the harshest climatological conditions. They are used in meteorological, atmospheric and other studies.


The pyregometer contains a thermopile which generates and output voltage when heated. This sensor sits beneath a silicon window which protects it from the environment and filters out all but the far infrared rays.
