Temperature Calibration

Garber Metrology’s precise and reliable temperature and humidity calibration services provide high-accuracy calibration according to industry standards.  We provide calibration services both in-house and on-site for your convenience. About 70% of our services are performed at customer facilities, while the rest are performed in our dedicated, environment-controlled laboratories. Our highly trained staff is equipped to produce precise temperature and humidity calibrations no matter where they are.

HOW TO CALIBRATE TEMPERATURE

Thermometers can take many forms, all of which may be tested in different ways. Generally, the best way to calibrate a thermometer is to physically heat or cool the sensors to a known temperature, then compare the output. If the thermometer does not provide the known temperature, it should be adjusted.

To properly calibrate a thermometer, the known heat source needs to be stable and uniform. It should not change over time or depend on where the thermometer’s sensors are located.

Common Types of Thermometer Calibration

There are three common types of thermometers that can be calibrated and adjusted in different ways based on how they take their measurements and produce results.

  • Infrared: To calibrate this equipment, our technicians use blackbodies — cavities with well-known emissivity values — and radiometers or radiometrically calibrated calibrators. They measure the infrared emissivity of the blackbody to determine the known temperature, then the infrared thermometer is tested to compare.
  • Digital: Digital thermometers are calibrated using either calibration baths or dry-block calibrators. Calibration baths are liquids heated or cooled to a stable, known temperature to calibrate the sensors’ accuracy. For dry-block calibration, thermometers are placed in a dry well that heats or cools to a stable temperature.
  • Liquid-in-glass: To calibrate these thermometers, our technicians use liquid calibration baths or dry-block calibrators. These methods both immerse the thermometer in a stable, known temperature to evaluate whether the reading is accurate.
