Wet heat test chamber is a kind of experimental equipment used to test the stability and durability of simulated articles in high temperature and high humidity environment. It can simulate the actual use environment under various humidity and temperature conditions to test the performance and durability of items in different environments.

Q&A
Temperature or humidity readings are inaccurate.

The temperature or humidity is unstable.

The device is not evenly heated or cooled.

The device is leaking or the tank capacity is insufficient.

An error occurred in program operation.

Calibration method
Temperature calibration: Place the thermometer in the test chamber and set the chamber to a known temperature. After waiting for some time, the thermometer reading is compared with the temperature reading displayed in the test chamber. If there is a difference, a calibration adjustment is required. Calibration can be done by adjusting the temperature calibration parameters in the controller.

Humidity calibration: Use a humidity calibrator to place it in the test chamber and set the test chamber to a known humidity. After waiting for some time, compare the humidity calibrator reading with the humidity reading displayed in the test chamber. If there is a difference, a calibration adjustment is required. Calibration can be performed by adjusting the humidity calibration parameters in the controller.

Equipment uniformity calibration: Place several thermometers or hygrometers inside the test chamber and set the test chamber to a known temperature or humidity. After waiting for a period of time, compare the readings at each measurement point to see if they are consistent. If there is a difference, a uniformity calibration adjustment is required. This can be achieved by adjusting the working mode and position of heating, cooling and fans, as well as adjusting the position of items inside the test chamber.

Equipment tank capacity calibration: Fill the tank in the test box with water and record the water capacity. Then set the test chamber to a certain humidity, measure for a period of time, and then pour out the tank and record the remaining water capacity. Subtract the remaining water capacity from the previously recorded water capacity to obtain the amount of water used by the test chamber at this humidity. If the amount of water used is not consistent with the capacity in the specification, a tank capacity calibration adjustment is required. It can be calibrated by adjusting the tank capacity parameters in the controller.

We you that the damp heat test chamber needs to be calibrated and maintained regularly. At the same time, it is necessary to regularly clean the inside of the equipment, check the performance and condition of the heating, cooling, control, sensors and other equipment, and timely replace or repair the faulty parts. In addition, it is recommended to maintain the device according to the operation manual and maintenance guidance provided by the manufacturer to ensure long-term stable operation of the device.

Precautions for use
In the process of using the wet heat test chamber, the following points should also be noted:

Reasonable arrangement of sample placement, to ensure that the sample can be subjected to uniform temperature and humidity distribution.

Do not accumulate too much debris or samples inside the test chamber to avoid affecting the operation of the equipment and the accuracy of the data.

According to actual needs, the temperature and humidity range and accuracy of the test chamber should be reasonably selected to avoid inaccurate test data due to mismatch of equipment parameters.

Before the test, pre-heat or pre-cool to ensure that the equipment can meet the required temperature and humidity conditions.

In the process of using the equipment, the temperature and humidity changes and test data are recorded in time, and analyzed and processed as required.

In short, the wet heat test chamber is a commonly used test equipment, but it is necessary to pay attention to the use and maintenance of the equipment during use to ensure the stability of the equipment and the accuracy of the test data.
