High low temperature test chamber is used to test the change of material under extremely high temperature and extremely low temperature environment that continue alternation in the shortest time, Testing the chemical changes or physical damage of material caused by the thermal expansion and contraction. Testing box divided two parts, one is high-temperature region, another is low-temperature region, the testing sample placed on the moving basket, using unique heat storage and cool storage, the cylinder taking basket moves up and down in the hot and cold region to complete the hot and cold temperature impact testing; applied to test the material, including metal, plastic, rubber, electronics and other materials, it can be used as a basis for improvement of their products.

1)  Use the high precision microcomputer touch temperature and humidity controller with high stability of platinum resistance to temperature and wind speed in the circulatory system of temperature and humidity test.

2)  Completely independent system separate for testing in high temperature, low temperature and constant temperature&humidity environment.

3) Rectangular complex glass window can be viewed the testing sample, windows with anti-sweat heater device that prevents water vapor condensation, and high-brightness PL light.

4) Built-in mobile pulley easy to move and has a strong positioning screw fixed position.
