The calibration of glass thermometers plays a decisive role in ensuring the reliability of measurement data. An inaccurate thermometer may lead to serious consequences such as incorrect experimental results and production deviations.
Detailed calibration steps: First, select a suitable standard thermometer with a higher accuracy than the glass thermometer to be calibrated. Preheat the constant temperature bath to reach the temperature of the first calibration point and keep it stable. Slowly insert the standard thermometer and the glass thermometer to be calibrated into the constant temperature bath, and the insertion depth should meet the requirements. Wait for a sufficient time for the thermometers to reach thermal equilibrium with the environment. Read and record the readings of the standard thermometer and the glass thermometer to be calibrated, accurate to the minimum scale value. Change the temperature of the constant temperature bath to other calibration points in turn and repeat the above operations. Finally, draw a calibration curve based on the recorded data to determine the correction values.
Calibrating strictly according to these steps can effectively improve the measurement accuracy of glass thermometers and provide a strong guarantee for accurate measurements in various fields.
