Altitude Test Chamber


Product Decription

Altitude test chamber is mainly used in aviation, aerospace, information, electronics and other fields, instruments and meters, electric products, materials, parts, equipment at the same time in the low pressure, high temperature, low temperature single or under the action of the environmental adaptability and reliability of the test, and or electric performance parameters for the specimen electricity measurement, adopt and composite structure form, the test chamber by is located in the front of the heat preservation box (confined structure), located at the back of the refrigeration, located on the chamber door vacuum unit and the electrical controller (system).


1.High performance and quiet operation
2.Space-saving designed for flush installation to wall
3.External pressure type box body structure and stainless steel tank design, rational air circulation system and scientific layout of 4.heating, refrigerating system
5.Adopts international brand of imported parts for cooling system to improve operation reliability
6.High precision and stable performance with touch screen controller, friendly Man-Machine interface.
7.Multiple layers of safety device to easy maintenance.

1.To simulate test environment with various altitude environments .
 2.It is especially important for defense and aerospace applications where pressure and vacuum 3.conditions are even more intense
Application fields: Include Aviation, aerospace, communications,  electronics, electrical appliances etc.

4.Test Purpose: to guarantee the maximum quality and reliability while  products or material might encounter at various altitude levels.
