Problems solved by technology

[0002] In the process of testing the performance of various industrial and mining products and military products (such as reliability, weather resistance), it is usually necessary to carry out environmental tests in specific equipment, such as high temperature environmental tests, low temperature tests in environmental test chambers or environmental test devices. Environmental test or damp heat environmental test; the existing environmental test equipment is usually composed of an environmental conditioning system, a test box for placing test samples and an air duct, and 220V lighting equipment is also installed on the test box, such as high temperature test box, low temperature test box, damp heat test box, etc. Test chambers and high and low temperature impact test chambers; although these test equipment have the characteristics of compact structure, easy control and convenient installation, the accuracy of the test results is poor, and they are used in the development of flammable and explosive dangerous industrial and mining products or bullets and arrows. The environmental test of military products has high risk factor and poor safety performance. For example, it is easy to ignite or detonate the test sample during the test. Once an explosion occurs, not only the test sample will be damaged, but the entire test equipment may be completely destroyed, causing severe damage. Large economic loss and possibly more serious injury to personnel
