Programmable Thermal Shock Test Chamber Environmental Test Equipment
Product Introduction:
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 equipment is widely used in metal, plastic, rubber, electronics and other materials and it can be used as an important reference for improving product quality. It meets the standard of MTL, IEC, JIS, GJB…
Features:
Perfect appearance and easy to operate.
Japan LCD English microcomputer temperature controller, with high memory capacity, can save 100 programs, max 9999 cycles, each cycle max time 999hrs.
Three chamber structures, high temperature chamber, low temperature chamber and test chamber, control automatically, stay and switch time adjustable.
Perfect protection alarm functions: short-circuits, Leakage, over temperature of work chamber; compressor over pressure, over load, short water…
Control interface will display alarm reason and provide check methods, machine has emergency stop button.
Cold and hot shock temperature recover within 5 minutes, which complies with MTL, IEC, JIS, GJB and other international standards.
With RS-232C communication port for connecting PC to control, record and save test report.
