The high and low temperature thermal shock test chamber is mainly used to test the performance of products during storage, transportation, and use in climate environments with instantaneous changes in high and low temperatures. Widely used in electrical and electronic products, components, parts, aerospace, metal and other materials, conducting repeated instantaneous change tests from high temperature to low temperature and then to high temperature. Through the test, the physical, mechanical and other performance changes of the tested object in the environment can be understood, which can be used to determine whether the product's performance can meet the design requirements, and provide useful data for product quality control, product improvement, etc.
control system
Controller: Programmable temperature controller, 7-inch true color LCD touch screen input, Chinese menu, PID self-tuning, data recording function, supports USB computer connection function, curve display function, etc., easy to operate.
