Pyrgeometers
Pyrgeometers are designed for IR (infrared) radiation measurement, for both atmospheric and material testing research applications.
The Kipp & Zonen range of pyrgeometers are designed to measure the atmospherically Far Infrared Radiation. The instruments have a silicon window with solar blind filter on the inside to block all solar radiation. The outside of the window is coated to protect it from environmental influences. A socket is fitted for the signal cable with waterproof plug.
The pyrgeometers are designed for permanent outdoor use under all weather conditions. An internal temperature sensor is available to calculate the downward Far Infrared irradiance.
CGR 3
Low cost pyrgeometer for accurate routine measurements in many applications.
CGR 4
The CGR 4 is designed for meteorological observations. The excellent thermal stability of the dome construction eliminates the need for dome temperature measurements or dome shading.
