Product Details

Programmable high and low temperature environment test chamberProduction testing method:

The high and low temperature test methods and industry standards can be divided into alternating test and constant temperature test, two types of test methods

Programmable high and low temperature environment test chamber

Alternating test chamber refers to the ability to set the required high and low temperatures, as well as the time required for the required temperature, within the instrument parameters at once. The test chamber will follow the set program, which is to set a fixed temperature to make the test effect closer to the natural climate, simulate more severe natural climate, and thus increase the reliability of the tested sample.

The selection of production environment and reliability testing equipment should follow the reproducibility of environmental conditions:

It is impossible to fully and accurately reproduce the environmental conditions that exist in nature in the laboratory. However, within a certain tolerance range, people can accurately and approximately simulate the external environmental conditions that engineering products undergo during use, storage, transportation, and other processes. This statement can be summarized in the language of engineering, which means that "the environmental conditions (including platform environment) created by the testing equipment around the tested product should meet the requirements of the environmental conditions and their tolerances specified in the product testing specifications. The temperature chamber used for military product testing should not only meet the high and low temperature test values and test times specified for different types of products in GJB150.3-86 and GJB150.4-86 standards, but also meet the requirements for temperature field uniformity and temperature control accuracy in the test specifications. Only in this way can the reproducibility of environmental conditions be ensured in environmental testing.

Programmable high and low temperature environment test chamber

Suitable for testing and determining the parameters and performance of electrical, electronic, and other products and materials after high temperature, low temperature, or constant temperature environmental changes.
