Hukseflux SR20

The SR20 is a high performing secondary standard pyranometer used for irradiance measurement at solar sites. It’s comparable to the Kipp & Zonen CPMP 11, but it’s a lower price point and tests indicates it is more accurate, particularly in low irradiance conditions. Traditionally, the instruments provide a millivolt signal and are best used in conjunction with something like a Campbell Scientific datalogger.
