The test principle of hot and cold impact test box
Apply to electronic, electrical equipment, vehicles, metals, chemicals, building materials, communication components, defense industry, aerospace industry, electronic chip IC, IT tests of a physical change. Hot and cold impact test cases by high temperature, low temperature area, test area of three parts, adopt unique insulating structure guarantee heat storage effect, is measured with the test perfectly still, switching application of hot and cold air duct into hot and cold gases, completed the high and low temperature cold heat shock test. Independently set high temperature, low temperature, cold and hot impact the function of the three different conditions, the execution of cold and hot shock conditions, choose the function of the three slot or two slot, possess the function of high temperature test chamber. Hot and cold impact test box in appointment start time control in the automatic preheating, ahead of precooling standby, selecting starting position, begin from high or low temperature cycle or temperature shock, set automatic defrost function of cycles.
Blow to exports and back to the detection and control of port sensor, the direction of the wind gate switch time completed within 10 s, cold and hot shock temperature recovery time of completion within 5 min. With temperature line will dc signal output to the temperature recorder, grasp the status of the testing conditions, improve the reliability of detection. Found the abnormal situation in the operation of hot and cold impact test box, screen immediately automatically show the cause of the problem and elimination method, found that the input power is not stable, there are emergency stop device. Hot and cold impact test box is widely used in electronic components, auto components, communication components, automotive components, metal, chemical materials, plastic industry, defense industry, aerospace industry, soldiers, BGA, PCB wrench, electronic chip integrated circuits, semiconductor ceramic and physical change in the polymer materials, the determination of its material of high and low temperature resistance and repeatedly product the chemical and physical damage caused by thermal expansion shrinkage, confirm the product quality, from precision IC to heavy machinery spare parts, both can be used as the basis and the reference of product improvement. The above explanation is the hot and cold impact test chamber, the test principle of hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
