Equipment summary:
Hot and cold impact testing machines used to test the change of material under extremely high temperature and extremely low temperature environment that continue alternation in the shortest time, Testing the chemical changes or physical damage of material caused by the thermal expansion and contraction. Testing box divided two parts, one is high-temperature region, another is low-temperature region, the testing sample placed on the moving basket, using unique heat storage and cool storage, the cylinder taking basket moves up and down in the hot and cold region to complete the hot and cold temperature impact testing; applied to test the material, including metal, plastic, rubber, electronics and other materials, it can be used as a basis for improvement of their products.
Main functions:
For electrical and electronic components, automation components, communication components, auto parts, metals, chemical materials and plastics industries, defense, aerospace, military industry, BGA, PCB base plate, electronic chip, IC, semiconductor ceramic and high-Changes in the physical sacrifice of molecular materials, test the material on the high and low tension and products arrived repeated thermal expansion and contraction of output in the chemical changes or physical injury, to confirm the quality of products, from the precision of the IC component to heavy machinery , And both need it the ideal test tool.
Main features:
1. Large color LCD touch interactive microcomputer control system, easy to understand, running at a glance;
2. Closed imported compressor + environmental refrigerant, cold plate heat exchanger and dual-type ultra-low temperature refrigeration systems;
3. A LAN network communication interfaces to computer remote control, easy to use;
4. Independently set the heat, cold and hot and cold conditions, the impact of three different function, the impact of the implementation of hot and cold conditions, with high and low temperature testing machine functions;
5. Operation at boot time automatically make an appointment ahead of pre-cooling, preheating, standby;
6. Defrost cycles can be set and the number of automatic (manual) defrost;
7. Controller friendly interface and easy procedure setting, abnormal and troubleshooting display complete.
