Reliability testing


Introduction of Environmental Test Laboratory:

In today's society, the market competition is increasingly fierce. The focus of competition among brand enterprises is not only on the function and appearance of products, but also on the quality and reliability of products. In recent years, environmental testing equipment has been invested more and more in environmental testing equipment, equipped with a variety of environmental testing equipment. By using various environmental testing equipment to simulate the temperature and humidity changes in the climatic environment, accelerating the failure of the product in the use environment, verifying whether it achieves the expected quality objectives in R&D, design and manufacturing, and providing overall evaluation for the product to determine the reliability life of the product.

HTT Environmental Test Laboratory has perfect safety and regulation testing equipment, the main equipment are imported international brands: with a number of large-scale constant temperature and humidity box, fast temperature change box, large drying box, shaking table, mechanical impact table, drop test, salt spray test, water-proof, dust-proof tester, and other environmental testing equipment.
