A28 Air Leak Tester

PA28
The air leak tester is a new type of non-destructive high-precision testing equipment. It mainly uses compressed air to apply a certain pressure to the outside or inner cavity of the product to be tested, and then detects the pressure change to determine the sealing of the product to be tested.
Product application areas: automotive, new energy, home appliances, consumer electronics, medical, aviation, outdoor security and valve body leak tester testing.

Overall Dimension

The differential pressure type supports seamless switching with ATEQ F28. Supports up to 32 groups of test parameter configurations and supports continuous testing of multiple groups of configurations. With 7 output ports and 6 input ports, it supports dynamic settings of IO ports without the need for additional PLC control. Supports multi-machine cascade testing, and cooperates with the Presun test application software to achieve multi-machine monitoring, test data statistical analysis, and database storage, etc. Compact size, very easy to embed in automatic equipment or assembly lines. Has higher cost performance and price advantages.
