Use:
The test chamber is suitable for high temperature, low temperature, high and low temperature cycle tests, as well as constant humidity and alternating humidity tests on products (complete machines), parts and materials. At the same time, after being connected with a vibration table, it can realize a comprehensive test of the three factors of temperature, humidity and vibration. This product is widely used in aviation, aerospace, shipbuilding, electronics, communications and other fields.
