Airtightness tester

Airtightness tester

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.
