The workpiece is immersed in a water tank, and the presence of continuous air bubbles is measured. Ultrasonic waves are used to precisely capture and pinpoint the leak point by detecting these bubbles. This method is widely used for sealing components in plastics and corrosion-resistant metals with cavities, achieving a detection accuracy of up to 1.0*10⁻⁵ mbar*l/s.

Vacuuming time is reduced by 40% compared to traditional equipment; leak rate accuracy reaches 1.0×10⁻⁸ mbar・L/s; 98% helium recovery rate significantly reduces consumable costs; 10%-99% adjustable detection concentration adapts to batch testing in multiple scenarios.

Clean air is introduced into the workpiece under test, and leakage is determined by measuring the internal pressure decay using a high-precision sensor.Supports SCCM leakage rate range of 0.01~0.1, with low cost, high efficiency and easy automation.
