Application of Rapid High and Low Temperature Test Chamber: The rapid high and low temperature test chamber is suitable for instruments, meters, electrical and electronic products. It is used to conduct adaptability tests and stress screening tests on electronic components, finished products, semi-finished products, semiconductors, chemicals, materials and other environmental testing machines and components under rapid or gradual temperature changes, in order to analyze and evaluate the performance and behavior of the test sample under the specified conditions (rapid changes) Complies with MIL-STAND.IEC and JIS testing standards. Product features: The rapid high and low temperature test chamber has a spacious and bright large electric observation window, which is composed of three layers of ultra large vacuum coating (heating film) windows and high brightness fluorescent lamps. It can clearly observe the test samples inside the chamber and effectively prevent the formation of water mist caused by internal and external temperature differences, allowing users to observe the conditions inside the test chamber at any time. Advanced safety and protection devices - residual current circuit breaker, dry burn protector, phase loss protector, refrigeration unit overpressure, overload, oil pressure and other protection devices.
