Many users consider a question when purchasing a double 85 constant temperature and humidity box, which is what kind of material should be used for the observation window of the equipment to ensure greater safety? Liuqin Technology received a call from a long-term cooperative customer who said that the observation window of a double 85 constant temperature and humidity chamber that I purchased from them was broken. They were very worried that their operators would come to check the changes in the situation inside the chamber at any time. In addition to understanding the material of the observation window, it is more important for us to know which products cannot be tested in the chamber because some products may contain flammable and explosive materials. In this case, no matter what material is used, the glass will shatter.

Our double 85 constant temperature and humidity chamber is made of glass and uses transparent electric heating film hollow tempered glass material. The reason why we purchase transparent glass is to facilitate the operator to observe the changes inside the test chamber more conveniently. We also consider the safety performance when using tempered glass. This material is reinforced with a pressure layer on the surface of the glass, which increases the heat and shock resistance of the glass. Therefore, it is called safety glass. Even when it breaks, this tempered glass does not fly like ordinary glass, it will become honeycomb like small particles, so it will not cause serious harm to the human body. Compared to ordinary glass of the same thickness, the impact resistance and bending strength of tempered glass are 3-5 times that of ordinary glass. It has good thermal stability and can withstand temperatures three times higher than ordinary glass, up to 200 ℃.

The temperature of the double 85 constant temperature and humidity chamber is -70 ℃ and+150 ℃, and tempered glass is used to ensure safety performance.
