- Comparing its readings to a reference thermometer that has been calibrated to a known standard
- Recording any discrepancies in temperature readings
- Thoroughly documenting the calibration process to ensure compliance with industry standards and regulations.
Different types of traceable thermometers require different calibration processes, and understanding these differences is crucial for maintaining the accuracy of your device. Let’s discuss the calibration processes for liquid-in-glass and bi-metal thermometers.
Calibrate Liquid-in-Glass Thermometers
Liquid-in-glass thermometers are calibrated by comparing their readings to a reference thermometer in a controlled environment. The reference thermometer should be traceable and conform to a national or international standard, such as NIST. This process ensures that your liquid-in-glass thermometer remains accurate and compliant with industry standards.
It is essential to use a controlled environment during calibration, as the temperature of the environment can influence the readings of the thermometer. Following the correct calibration process for liquid-in-glass thermometers ensures their accuracy and dependability in temperature measurement.
Bi-Metal Thermometers Calibration
Bi-metal thermometers are calibrated by adjusting the thermometer’s dial to match the temperature of a reference thermometer. The reference thermometer should also be traceable to a national or international standard, such as NIST. This process ensures that your bi-metal thermometer remains accurate and compliant with industry standards.
Adhering to the correct calibration process for bi-metal thermometers guarantees their accuracy and dependability in temperature measurement. It is essential to document the calibration process to maintain compliance with industry regulations and traceability standards.
