Features

Dimensions

Apogee Instruments’ MI series infrared temperature meters are calibrated to the temperature of a custom blackbody cone held at multiple fixed temperatures over a range of radiometer (detector/sensor body) temperatures. The temperature of the blackbody cone is measured with replicate precision thermistors thermally bonded to the cone surface. The precision thermistors are calibrated for absolute temperature measurement against a platinum resistance thermometer (PRT) in a constant temperature bath. The PRT calibration is directly traceable to the National Institute of Standards and Technology (NIST).

Calibration Traceability

HIGH ACCURACY

Calibrated to a custom black-body cone with a measurement uncertainty of ± 0.2 C from -30 to 65 C when the sensor temperature is within 20 C of the target. Radiometers are only sensitive to wavelengths from 8 to 14 μm to minimize the influence of water vapor and CO₂ on the measurement.

RUGGED HOUSING

Anodized aluminum body with fully-potted electronics. The outer radiation shield reduces thermal fluctuations.
