Different calibration methods of glass thermometers

There are various ways to calibrate glass thermometers. A common one is the overall calibration method. This method puts the thermometer as a whole into a specific temperature environment and calibrates by comparing with the standard temperature. For example, put the thermometer into a constant temperature bath with the temperature set to a known standard temperature. After waiting for a while, read the thermometer's reading and compare it with the standard temperature.


There is also the local calibration method, which calibrates a specific part of the thermometer. For instance, calibrating the temperature - sensing bulb of the thermometer by immersing it in a liquid with a known temperature and observing its temperature change to adjust the calibration.


In addition, using electronic calibration equipment can achieve fast calibration. These devices measure the temperature of the thermometer through sensors and compare it with the standard temperature, automatically adjusting the calibration.


Different calibration methods are suitable for different scenarios, and choosing the right method can improve the calibration efficiency and accuracy.
