Working Principle

This is so called three-zone type thermal shock test chamber.
Sample is placed in the test chamber, more extreme temperature than test temperature can be set in high-temperature chamber and low-temperature chamber. When it comes to low temperature test, cold chamber door open, and low-temperature chamber working together with test chamber.
When converted into high-temperature test, cold chamber door closed, hot chamber door are opened, and test chamber working together with high-temperature chamber.
Conversion of mechanical action (transferring from high temperature to low temperature or low temperature to high temperature) can be completed in less than 1second, and the temperature can be quickly stabilized.
During the whole test, test sample is no need to be moved, and without any human intervention.

Applications

2-zone Thermal shock chamber have been designed to operate in accordance with reliability programs, quality control, commercial test programs and medical tests. It is used to test the capability of material structure or composite material to withstand the continuous environmental changes between extremely high temperature and low temperature during a short period. It is applicable to metals, plastic, rubber, electronics amongst other materials. The test result can be used as a reference or basis for produce improvement.

Features

1.Thermal shork chamber in each zone for peak demand of heating and cooling. Provides extra thermal energy to efficiently meet the MIL-STD 883 requirements.
2.Temperature recorder provides 24 hour part temperature recording as the load travels from zone to zone. Using touch-control graph control as operation interface, easy to operate.
3.The system can be used for automatic Circulation Shock or manual selective shock, capable of setting two zones or three zones shocks as well as cold and thermal shock start-up.
4.Custom-made and optional accessories available.
