The process of glass thermometer calibration is as follows:
First of all, prepare the equipment and tools required for calibration, including standard thermometer, constant temperature bath, alcohol cotton balls, etc.
Secondly, check the appearance of the thermometer for any damage or abnormal conditions. If there is damage, it should be replaced in time.
Then, place the thermometer into the constant temperature bath to ensure its temperature - sensitive part is completely immersed in water. Wait for the thermometer reading to stabilize.
Next, read the thermometer reading and compare it with the standard thermometer. Record the temperature deviation value.
Finally, adjust the thermometer according to the deviation value. If the deviation is large, the calibration can be carried out by adjusting the scale of the thermometer or replacing the temperature - sensitive part of the thermometer.
During the calibration process, pay attention to keeping the thermometer clean and dry, and avoid affecting the calibration results due to impurities or moisture. At the same time, strictly follow the calibration operation steps to ensure the accuracy and reliability of the calibration.
