DERAY®-Leakage Tester

The DERAY®-Leakage Tester is a testing device designed for the leaking test of wire applications assembled with heat shrink tubes.
Using compressed air and four test chambers it can leakage test up to 20 cables at once.

Features and Benefits

  • Process optimization possible by simultaneous testing of up to 20 cables for leaks
  • Automatic self-testing based on predefined parameters for leakage and pressure-sensor tests
  • High flexibility through testability of cable diameter from 0.13 mm2 – 10 mm2
  • Reliable test procedure because of pressure monitoring in each test chamber
  • Adjustable parameters: Testing time, pressure
  • Pressure for standard tests: 0.5 – 1.0 bar
  • Selection of system language: English, German, French, Polish, Romanian (others on demand)
  • CE and RoHs conformity


Parallel and end splice, ring- and tubular terminal applications, battery terminals


The cables to be tested are placed in a chamber of the DERAY®-Leakage tester filled with water. A maximum of 20 cables can be tested simultaneously, using 4 test chambers that each secures up to 5 cables. The test pressure can be set to 0.5 – 1.0 bar according to the test procedure. The inspection process is activated by simultaneous closing of the safety hoods. The four pressure chambers located under the protective covers close automatically and the pre-selected pneumatic test pressure begins to build up. Leaks in crimped or welded lines and those fitted with heat shrink tubing will become visible through rising bubbles in the water. After the process is completed, the safety hoods and pressure chambers are automatically opened, and the cable-fastener is automatically unlocked.
