The cost - benefit of glass thermometer calibration is reflected in multiple aspects. From the cost perspective, the cost of equipment, tools, and professional personnel required for calibration is the main cost. Purchasing high - precision calibration equipment may cost a certain amount of money, and regular maintenance of the equipment are also needed to ensure its normal operation. In addition, materials consumed during the calibration process such as alcohol cotton balls and standard substances also increase the cost.
However, the benefits brought by calibration are also significant. Accurate thermometers can improve the quality and efficiency of the production process and reduce the waste rate. For example, in the pharmaceutical industry, accurate temperature control is crucial for the quality of drugs. Calibrated thermometers can avoid product quality problems caused by temperature deviation, thus reducing losses. In the scientific research field, calibrated thermometers can provide more reliable experimental data, which is helpful for the promotion and application of scientific research results.
Overall, although calibration requires certain costs, by improving the accuracy and reliability of thermometers, it can bring long - term economic and social benefits.
