How to choose this product

The pyrheliometer measures solar radiation incident within a band of just a few degrees. It is similar to the pyranometer, though the latter measures solar radiation falling on a surface and has an angle of view of 180°.


This device is a field instrument designed for use in even the harshest climatological conditions. It is found at weather stations and photovoltaic installations, and in atmospheric, climatological and other research.


This instrument uses a narrow tube to limit the sensor's field of view. As in a pyranometer, this sensor is a thermopile which produces an output voltage when heated by the sun's rays. Its narrow angle of view requires the pyrheliometer to be linked to a solar tracker.
