With the rapid development of industry and military equipment, improvements to the quality and reliability of products have become increasingly demanding, and thus the reliability of the research equipment - Environmental test equipment made more higher requirements.

1. explore and identify single or multiple environmental factors on the impact assessment of products, environmental adaptability;

2. pilot projects as a product of the type one, or product acceptance test, to see whether they meet the requirements of the environmental requirements, the product is qualified as product acceptance or rejection decision making .

environmental test equipment is to expose the natural environment or artificial environment, they will actually encounter storage, transport and use, and performance under special environmental conditions make assessment . Through environmental testing, can provide manufacturers with design quality and product quality aspects of information, is an important means of quality assurance.
