Calibration Services

Blackbody Radiators, Radiation Thermometer Calibrators and Infrared Ear Thermometers Calibrators emit thermal energy as given by the Planck law of radiation. They can be used to calibrate radiation thermometers or infrared ear thermometers.

Blackbody Radiators, Radiation Thermometer Calibrators and Infrared Ear Thermometers Calibrators are calibrated by comparison with reference blackbody radiators of the Laboratory. The Laboratory can provide calibration services from -40°C to 200°C.

 

Radiation thermometers (or infrared thermometers) are non-contact thermometers that measure the thermal energy radiated from the surface of the source. The temperature is related to the thermal energy by the Planck law of radiation.

Radiation thermometers are calibrated by using blackbody radiators. The Laboratory can provide calibrations for radiation thermometers from -40°C to 1000°C.

 

The eardrum is close to and shares blood with the temperature control centre in the brain. The temperature of the eardrum reflects the core body temperature. Infrared ear thermometers measure the thermal energy radiated from the surface of the eardrum at wavelengths around 10 µm. Infrared ear thermometers are calibrated by using blackbody radiators.

During normal use, the sensor of the infrared ear thermometer is covered with a lens filter. The thermometer will be calibrated with the lens filter put on. New and clean lens filter should be submitted with the thermometer.
