Two-box thermal shock test chamber, high and low temperature impact environment testing machine
The thermal shock test chamber, also known as the environmental test machine, tests various materials for heat resistance, cold resistance, dry resistance and moisture resistance. Suitable for electronics, electrical appliances, food, vehicles, metals, chemicals, building materials and other factories.
Control methods and features :
The thermal shock test chamber utilizes low temperature and high temperature cold storage hot tanks to move the basket quickly into the hot and cold tank according to the action requirements , so as to achieve rapid temperature impact effect , balance temperature control system ( BTC ) + special design air supply circulation system to the SSR PID controlled, so that the amount of heat equal to the amount of heat loss of the system, so that long-term stable use.
