Precautions for glass thermometer calibration
Source: | Author:Olivia | Published time: 2025-01-03 | 49 Views | Share:
The following precautions should be noted during the glass thermometer calibration process:
Firstly, ensure the thermometer is clean before calibration. Use alcohol cotton balls to wipe the surface of the thermometer to remove dust and impurities.
Secondly, the calibration environment should be stable. Avoid large temperature fluctuations and try to maintain a constant temperature environment.
Thirdly, operate correctly during the calibration process. For example, when the thermometer is immersed in the liquid, ensure it is vertical and the depth is appropriate, and when reading the thermometer, the line of sight should be parallel to the thermometer scale.
In addition, the calibration equipment should be regularly checked and maintained. Ensure the accuracy and reliability of the equipment.
Finally, record the calibration results. Include information such as calibration date, calibration method, temperature deviation, etc., for convenient future reference and analysis.
