For testing the degree to which a material structure or composite material can endure instantaneous and continuous exposure to extremely high and low temperatures in order to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest possible time. Suitable for testing physical changes in electronics, vehicles, metals, chemicals, building materials, communication components, defense industry, aerospace industry, electronic chips IC, IT, etc.
1, the test system structure design is advanced and reasonable, GB/T 2423.1-2001, GB/T 2423.2-2001, GB/T 2423.22-2001, GJB 150.3-2001;
2, the main functional components of the test chamber used world-famous brand configuration, advanced and reliable technical principles, noise and energy saving to get the best control - its performance can replace similar foreign products;
3, the whole machine refrigeration system using PID algorithm control, without the need to add a heating tube to consume extra power, power saving up to 35%;
4, the equipment has good operability, maintenance, good temperature stability and durability, good safety performance, no pollution of the environment and personal health hazards;
5, change the traditional hot and cold confrontation control method, using the latest cold balance control technology, which can achieve 500 ~ 1000 cycles without frosting, improve efficiency, save test time, more power saving, energy saving, and environmental protection;
