What are the FAQs of the Environmental Test Chamber? How to calibrate?

The environmental Test Chamber is an experimental equipment used to simulate the performance and durability tests of items under different environmental conditions. It can simulate different environmental factors such as temperature, humidity, light, vibration, pollution, etc., to test the performance and durability of items in different environments.

common problem

1. Inaccurate temperature or humidity readings.

2. Unstable temperature or humidity.

3. The device is heating or cooling unevenly.

4. The device is leaking or the Water Tank is insufficient.

5. An error occurred in program operation.

Calibration method

Temperature or humidity calibration: Place a thermometer or hygrometer in the environmental chamber and set the chamber to a known temperature or humidity. After waiting a period of time, compare the thermometer or hygrometer reading with the temperature or humidity reading displayed by the environmental chamber. If there is a difference, a calibration adjustment is required. Calibration can be done by adjusting the temperature or humidity calibration parameters in the controller.

Equipment uniformity calibration: Place several thermometers or hygrometers inside the environmental Test Chamber, and set the environmental Test Chamber to a known temperature or humidity. After waiting for a period of time, compare whether the readings of each metering point are consistent. If there is a difference, a uniformity calibration adjustment is required. This can be achieved by adjusting how and where heating, cooling and fans work, and by adjusting the position of items inside the environmental chamber.

Equipment Water Tank capacity calibration: fill the Water Tank in the environmental Test Chamber with water, and record the water capacity. Then set the environmental Test Chamber to a certain temperature or humidity, after measuring for a period of time, pour out the Water Tank and record the remaining water capacity. Subtract the previously recorded water capacity from the remaining water capacity to get the amount of water used by the environmental Test Chamber at that temperature or humidity. If the amount of water used is inconsistent with the capacity in the specification, a Water Tank capacity calibration adjustment is required. It can be calibrated by adjusting the Water Tank capacity parameter in the controller.

Beichao reminds you: the environmental Test Chamber needs to be calibrated and maintained regularly. At the same time, it is necessary to regularly clean the interior of the equipment, check the performance and condition of heating, cooling, control, sensors and other equipment, and replace or repair problematic parts in time. In addition, it is recommended to carry out maintenance according to the operation manual of the equipment and the maintenance instructions provided by the manufacturer to ensure the long-term stable operation of the equipment.

Precautions

In the process of using the environmental Test Chamber, you also need to pay attention to the following points:

1. Reasonably arrange the placement of samples to ensure that the samples can be subjected to uniform temperature or humidity distribution.

2. Do not accumulate too much sundries or samples inside the environmental Test Chamber to avoid affecting the operation of the equipment and the accuracy of the data.

3. According to actual needs, reasonably select the temperature or humidity range and accuracy of the environmental Test Chamber to avoid inaccurate test data due to mismatching equipment parameters.

4. Before testing, it is best to preheat or precool the equipment to ensure that the equipment can reach the required temperature or humidity conditions.

5. During the use of equipment, timely record temperature or humidity changes and test data, and analyze and process them as needed.

In short, the environmental 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.
