We know that the constant temperature and humidity chambers are equipped with glass windows, so that the changes of the conditions in the chamber can be clearly observed during the test, but the thermal shock test chambers are not equipped with glass windows, why? Is this the inhumane design or poor consideration by the manufacturer? In fact, the manufacturer deliberately did not design the glass windows for the thermal shock test chambers.

The truth is that the temperature conversion of the thermal shock test chamber is instantaneous. The conversion from high temperature to low temperature does not exceed 5 minutes. Similarly, the conversion from low temperature to high temperature does not exceed 5 minutes. It is a severe test for the test product. If a vacuum glass window is installed, the glass window will also be subjected to this severe test. Unlike stainless steel, glass is easily broken when subjected to this high temperature and low temperature instant conversion test for a long time.  Therefore, we generally do not recommend that users install glass windows on the door of the thermal shock test chamber.

But what if the user must request to install a glass observation window on the thermal shock test chamber? We can also design and install a glass observation window according to the user’s requirements, but the glass window needs to be replaced every 2-3 years, and the user should be  willing to bear this after-sales cumbersome and loss.
