Product Features
Adopting fully automatic PID control, it has high precision and can save 30% electricity,
The three box equipment is divided into three parts: high temperature zone, low 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 tube is easy to operate.
※ The impact method applies the air path switching method to import the temperature into the testing area for conducting cold and hot impact tests.
During high or low temperature impact, the maximum time can reach 999H and the maximum cycle period can reach 9999 times.
The system can be used for automatic cycling 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, which has a fast cooling effect and is water-cooled.
Three boxes can be tested for impact at room temperature,
High and low temperature conversion time: within 10 seconds (other requirements to be agreed upon)
Implement standards and test methods that meet the requirements: GJB150.5 temperature shock test; GJB360.7 temperature shock test; GB/2423.22 Temperature Shock Test
