Infrared Radiometers

Apogee Instruments, Inc. (Apogee)

Calibrated to a custom black-body cone with a measurement uncertainty of 0.2 C from -30 to 65 C when the sensor (detector) temperature is within 20 C of the surface (target) being measured. Radiometers are only sensitive from 8 to 14 m (atmospheric window) to minimize the influence of water vapor and CO2 on the measurement.
