High and low temperature alternating test chamber
Our company is mainly committed to the R&D and production of high and low temperature alternating test box, and is a professional test equipment limited company that combines R&D, production and sales. This machine is specially used to test the heat, cold, dry and wet resistance of various materials. This machine can select Chinese or English LCD to display touch screen, which is easy to operate and program editing. It can display complete data related to system operation status, execution and setting program curve. In case of any abnormal condition during operation, the screen will automatically display the cause of the fault and provide troubleshooting methods.
It is suitable for testing the quality of electronic, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical... and other products.
