TESTING Testa_e TS3055W 3-ZONES THERMAL SHOCK CHAMBER

• • • • 3 ZONES TEMPERATURE SHOCK TEST CHAMBER• This system features a three-zone structure enabled by damper switching, allowing samples to remain in place and be tested via cable connection. Easily switch between two-zone and three-zone operation, and expose samples to ambient temperature when needed. Air outlet Machine room High temperature room Test room Power distribution room Operation panel General power panel High temperature room: for the storage of heat. Test room: for the placement of test sample and execution of test. Low temperature room: for the storage of cold energy. General power...
