High low temperature/ low air pressure test chamber
This chamber is designed to test products and materials to the effects of high and low temperature (and humidity), and low atmospheric pressure.
The choice of equipment depends on many factors:
◆ The size and weight of the test product;
◆ Requirements of test modes (graphics) - complexity, speed of changes in temperature and / or humidity parameters, pumping time, duration-regulated by Russian or other standards, including international standards;
◆ The presence of heat from the test product;
◆ Individual technical requirements, for example, specifications of a specific product.
