Available in two grades (research and commercial with ± 0.2C and ± 0.5C accuracy respectively) and a variety of outputs, the Apogee infrared radiometers are NIST traceable with an included calibration certificate.

The research grade sensors have 5 fields of view (three circular and two horizontal), and the commercial grade has a single field of view.

Capable of measuring plant canopy temperatures, as well as the temperatures of surfaces such as roads, soils, water and snow, the applications of the infrared radiometers are varied.
