The principle of hydration of calorimeter

During the operation of the calorimeter, some components will consume water due to heat exchange, evaporation, etc. Like the oxygen bomb calorimeter, the inner cylinder water participates in heat transfer during testing. If the amount of water is insufficient, it will affect the accuracy of heat conduction and lead to deviations in the test results. Therefore, in principle, the calorimeter has a need to replenish water, which is the basis for ensuring its accurate measurement.

When do you need to rehydrate the calorimeter?

When it is found that the water level of the inner cylinder of the calorimeter is lower than the specified scale line, or the instrument frequently experiences unstable testing and large data fluctuations, it is necessary to consider replenishing water. In addition, regular inspection is also the key. It is recommended to check the water level before each use to ensure that the water volume is within the normal range to avoid instrument failure due to water shortage and affect the experimental progress.

Correct operation of calorimeter replenishment

Before replenishing water, turn off the power of the instrument to ensure safe operation. Use distilled water or deionized water to avoid impurities in the water affecting the performance of the instrument. With the help of a special replenishment device, slowly fill the inner cylinder with water until the water level reaches the specified scale. After replenishing water, turn on the instrument for air measurement to observe whether the data is stable and confirm the replenishment effect.

Maintenance points after hydration

After the water replenishment is completed, the calorimeter needs to be cleaned to wipe the external water stains to prevent the parts from rusting. At the same time, regularly check whether the water replenishment device is blocked or leaking to ensure smooth water replenishment next time. Establish a water replenishment record to record the time and water volume of each replenishment, which is convenient for tracking the status of the instrument and finding potential problems in time.

Mastering the knowledge of hydration of the calorimeter is the key to ensuring the accurate operation of the instrument and prolonging its service life. Follow the correct operation and maintenance procedures to allow the calorimeter to continuously provide you with reliable data.
