~Introduction:
thermal shock environmental chamber could be used for all types of electronic products, electric appliance, and products from communication,instrument,automobile,plastic,metal,food,chemical,building materials, medical and aerospace industries, to test the performance index under high and low temp. rapid change environment condition for quality inspection management.

Features:
The thermal shock test machine is divided into three sections: The high temperature chamber, the low temperature chamber and the testing chamber.
The color touch panel control system was made in Doaho in shanghai china, can display Chinese / English etc. The big size liquid-crystal LCD has been adopted.
High formula memory capacity may be set to 120 patterns. The maximum cycle setting is 9999cycles. The maximum setting of each section is 999 Hrs 59 Mins.
Provide with RS-232C communication interface device, capable of controlling / editing/ recording in the linkage with the computer and two set dynamic connection point and convenient application.
Both 2 zone and 3 zone shocks can be chosen.
All equipment is fully automatic, and all process are precisely controlled with P. L. C. 'S.
Of any part of the malfunctions, the machine will automatically shuts down and a warning light switches on.
Machine can be shut down automatically in case of electrical power instabilities
