ELT500 is non-destructive testing equipment with high precision, which uses compressed air as a medium to apply a certain pressure to the inner cavity or surface of the product to be tested, and then uses a high-sensitivity sensor to detect pressure changes to determine the tightness of the product.


The ELT500 is an extremely precise, non-destructive device for checking air leaks. It mainly uses compressed air to check vehicles with high-voltage batteries for leaks. Once a stable pressure is reached in the vehicle’s high-voltage battery, the ELT500 automatically initiates the maintenance phase. Using its highly sensitive pressure sensor, any changes in the holding or maintenance pressure within the high-voltage battery are detected and displayed on the LCD screen. To identify leaks, the ELT500 uses a differential pressure measurement method.




High sensitivity

The highly sensitive pressure sensor technology significantly improves test accuracy and stability.

Process visualization

The progress time of each phase of the test process can be displayed on the screen.

Double display of the pressure value

Real time display of the pressure scale and the pressure curve of the process.

Parameter management

Real time display of the pressure scale and the pressure curve of the process.

Setting the parameters

Parameters such as number of parts, volume, pressure, time of each stage and leakage limit can be preset.

Intelligent alarm

The unit will give an audible and visual alarm if the test is abnormal or fails.
