Second class albedometer ISO9060
The PCTRA054 albedometer is manufactured using 2 second class pyranometers (according to ISO9060 and WMO standards). The albedometer uses 2 identical opposing pyranometer: one facing upwards (sky) the other facing downwards (ground).
The first measures the incoming global radiation (direct + diffuse), while the second measures solar radiation reflected from the surface below.
Electrical output of the two pyranometers (the two pyranometers used in the PCTRA054 are coupled so to have the same sensitivity) can be acquired by a datalogger or automatic data elaboration unit.
