Thermal Shock Test Chamber Introduction:
Hot and cold impact chamber can be repeated quickly and autonomously to the pattern in the cold and hot environment between the hot and cold cycle test. Equipment can quickly and accurately create a hot and cold environment with -40~175°c temperatures ranges.
Thermal Shock Test Chamber is used to test the bearing extent of the material structures and composite material in an instant and continuous high temperature and extremely low temperature environment, which is in the shortest time to test its thermal expansion and contraction caused by chemical change or physical harm.
The thermal shock chamber is widely used in metal, plastic, rubber, electronics and other materials and it can be used as an important reference for improving product quality.
Features:
1. Perfect appearance and easy to operate.
2. Imported LCD English microcomputer temperature controller, with high memory capacity, can save 100 programs, max 9999 cycles, each cycle max time 999hrs.
3. Two chamber structures, high temperature chamber and low temperature chamber, control automatically, stay and switch time adjustable.
4. Perfect protection alarm functions: short-circuits, Leakage, over temperature of work chamber; compressor over pressure, over load, short water…
5. Control interface will display alarm reason and provide check methods, machine has emergency stop button.
6. Cold and hot shock temperature recover within1 minute, which complies with MTL, IEC, JIS, GJB and other international standards.
