The constant temperature and humidity test chamber is used to test the parameters and performance of electronic and other products after the temperature and humidity changes.
In order to better exert the effect of the constant temperature and humidity test chamber, it is important to debug and calibrate the chamber for 10-15 days before leaving the factory. The following are the 3 methods for calibration of the constant temperature and humidity test chamber and their advantages and disadvantages.
1. Calibrate under load conditions
Advantages: It can more accurately evaluate the impact of the test sample on the performance of the test chamber, and it is easy to get the detailed information of the environmental test of the key components or parts of the test sample.
Disadvantages: When the test sample is replaced, it needs to be re-calibrated.
2. Calibrate under no-load conditions
Advantages: The entire working area of the programmable constant temperature and humidity test box has been calibrated, and the applicability of the test box can be effectively evaluated.
Disadvantages: The influence of the test sample on the test chamber cannot be evaluated.
3. Real-time measurement during use
Advantages: not only has the advantages of the above-mentioned method. In addition, it is possible to obtain comprehensive environmental parameters of the test sample in the environmental process, which is often used in the test of products with high environmental requirements.
Disadvantages: All environmental tests need measuring equipment, and the calibration method under no-load conditions is usually used when the test chamber is calibrated.
