Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: The three box equipment is divided into three parts: high temperature zone, ow temperature zone, and testing zone. The test product is placed in the testing zone, and the temperature of the high or low temperature zone is flushed into the testing zone for impact. The test product is static. Adopting a touch based graphical control interface, the operation is simple. impact methods apply the air path switching method to import the temperature into the testing area for conducting cold and hot impact tests. When subjected to high or low temperature impacts, the maximum time can reach 999H and the maximum cycle period can reach 9999 times. The system can be used for automatic cycle engine or manual selective impact, and can set the start of three zone impact, cold impact, and hot impact. The cooling system adopts a binary freezing system with fast cooling effect, and the cooling method is water-cooled
