CGR3 Pyrgeometer

The CGR3 is a pyrgeometer, designed for meteorological measurements of downward atmospheric long wave radiation. The CGR3 provides a voltage that is proportional to the net radiation in the far infrared (FIR). By calculation, downward atmospheric long wave radiation is derived. For this reason CGR3 mbodies a temperature sensor. The CGR3 uses a specially designed silicon window. On the inside a solar-blind filter blocks solar radiation. The CGR3 data represents the radiation exchange within the whole hemisphere. This is because the reference CGR3 is calibrated outdoors with respect to a reference CG4, which has a 180 degrees field of view.

The CGR3 has been improved in many points over the CG3, based on customer feedback and years of experience. The CGR3 has a newly designed sunscreen that covers both body and connector to reduce the instrument temperature and further increase the accuracy. The design of the instruments accounts for the use of existing Kipp & Zonen mounting plates.

The base of the instruments contains the mounting holes, a spirit level and levelling feet for exact levelling. For ease of mounting, exchange and recalibration the instruments have a waterproof connector. The standard supplied 10 m. shielded cable has the waterproof sealed counterpart connector. The improved temperature dependency and directional response make these instruments the ideal choice for meteorological and agricultural applications.
