Description

APPLICATION

Thermal shock testing subjects a product to alternating extremes of high and low temperatures in order to observe changes in the product’s characteristics and failure occurrences caused by different materials and thermal expansion.

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 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.
