    Digital Leak Detector

    Overview Knowledge Standards Terms
    The digital leak detector uses sensors to detect ultrasonic signals generated by gas leaks and converts them into a digital display. It is used to locate minor leaks in pipelines and seals, and is employed in HVAC and automotive manufacturing to inspect the airtightness of air conditioning systems and fuel tanks.
    Selection
    When selecting, focus on a detection frequency range covering 20–100 kHz, with sensitivity reaching -10 dB. Choose the probe type based on whether contact or non-contact is required. Consider environmental noise suppression capabilities and the instrument's protection rating. The battery life should support continuous operation for over 4 hours.

    Negative pressure method leak detector for testing vacuum packaging seal integrity
    The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
