Kipp & Zonen CGR Pyrgeometer

Kipp & Zonen CGR Pyrgeometer er en transducer til præcis måling af ‘Far Infrared Thermal Radiation’ (FIR). Pyrgeometer CGR måler den indkomne termiske stråling fra himlen/rummet og skyer, samt den udgående termiske stråling fra jorden. Derved findes jordens termiske balance. CGR4 og SGR4 er præcisions pyrgeometre og er godkendt af WMO.
