Different leak testing methods are employed and innovatively advanced at GEIGER Automotive.

• Integral hydrogen leak test: A hood in which the test gas collects is required for this test. During the automatic test cycle, a measuring probe takes a sample of the gas from the inside of the hood. The sensor subsequently informs the user of the leakage rate.
• Integral helium leak test: Test object and test chamber are evacuated. The test specimen is exposed to helium. Helium is detected inside the chamber. As the helium enters a vacuum, it spreads very quickly.
• Integral test with laser: A test gas is admitted to the detection cell. The detection cell has windows through which the laser beam can pass. If the test gas is detected in the detection cell, its concentration can be determined and hence the leakage rate calculated.
