Humidity chamber FAQ and correct calibration method

The high-low temperature humidity Test Chamber is a kind of experimental equipment used to simulate the stability and durability test of items under high temperature and high humidity, low temperature and low humidity and temperature and humidity cycle conditions. It can simulate the actual use environment under various humidity and temperature conditions 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

1. Temperature Calibration: Place the thermometer in the chamber and set the chamber to a known temperature. After waiting for a period of time, compare the thermometer reading with the temperature reading displayed by the Test Chamber. If there is a difference, a calibration adjustment is required. Calibration can be performed by adjusting the temperature calibration parameters in the controller.

2. Humidity Calibration: Use a humidity calibrator to place in the chamber and set the chamber to a known humidity. After waiting for a period of time, compare the humidity calibrator reading with the humidity reading displayed by the Test Chamber. If there is a difference, a calibration adjustment is required. It can be calibrated by adjusting the humidity calibration parameters in the controller.

3. 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 whether the readings of each metering point are consistent. If there is a difference, a uniformity calibration adjustment is required. This can be done by adjusting how and where the heating, cooling and fans work, and by adjusting the position of items inside the Test Chamber.

4. Equipment Water Tank capacity calibration: fill the Water Tank in the Test Chamber with water, and record the water capacity. Then set the Test Chamber to a certain 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 obtain the amount of water used by the Test Chamber at that 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. North and South Chao reminds you: the high-low temperature humidity and heat 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 for use

In the process of using the high-low temperature humidity Test Chamber, the following points should also be paid attention to:

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

2. Do not accumulate too much sundries or samples inside the 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 and humidity range and accuracy of the Test Chamber to avoid inaccurate test data due to mismatching equipment parameters.

4. Before testing, perform preheating or precooling to ensure that the equipment can reach the required temperature and humidity conditions.

5. During the use of the equipment, the temperature and humidity changes and test data are recorded in time, and analyzed and processed as needed.

In short, the high-low temperature humidity 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.
