Product Details

It is applied to test the materials in heat-resistance, cold-resistance, dry-resistance, moisture-resistance. It is simple to operate and program easy to edit. It can show the set values and operative time.


Applied to test the prodcuts quality, such as electronic, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical care and so on.


The three-in-one design makes the equipment easy to operate and space-saving.Users can do different testings of high temperature,low temperature and costant temperature humidity condition in every single testing area.


Every system is entirely independant of each other,adopts 3 sets of refrigeration systems,3 sets of humidifying systems and 3 sets of controlling systems,so as to ensure stable and accurate controlling,and povide a longer service life.


Touch control & setting mode is totally controlled and locked up by automatic micro computer system with PID value automatic calculating ability.
