Thermal shock tester is used in photovoltaic modules, LED tubes, LED lamps, electronic and electrical components, automation components, communication components, auto parts, metals, chemical materials, plastics and other industries. To test the chemical changes or physical damages caused by thermal expansion and contraction due to the extreme high and low temperatures. From precision IC to heavy mechanical components, the programmable thermal shock test chamber is required.
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 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.
