Constant temperature and humidity test room
Our company is mainly committed to the research and development and production of constant temperature and humidity box. It is a professional testing equipment limited company that combines research and development, 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.
The constant temperature and humidity test room is a necessary test equipment in the fields of aviation, automobile, household appliances, scientific research, etc., used to test and determine the parameters and performance of electrical, electronic and other products and materials after high temperature, low temperature, alternating humidity and heat or constant temperature environment changes.
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.
