Talking about the change of temperature deviation during the test of high and low temperature test chamber

In the natural environment, there are more and more reasons for the temperature deviation of metal equipment, and a single product can not prevent this from happening. Therefore, in order to make the experimental results meet the test samples under natural environmental conditions, the performance of the test in China is not affected by temperature deviation. The high and low temperature test chamber was re-developed and reformed to raise it to the latest version.
