High low temperature test chamber
High low temperature test chamber is used when working with high and low temperatures.
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 parameters, 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.
