    Helium Sniff Leak Detection: A highly accurate and sensitive leak detection method where helium is used to charge parts to a specified pressure level. Once pressurized, a sniffer device scans the surface to detect leaks. It is effective for air leak testing but might not detect leaks that fall below the testing sensitivity level.

  • Dansensor LeakMatic II - Tendring Pacific

    The vacuum produces a pressure difference between the inside of the packages and the test chamber, causing CO 2 from the package to escape into the test chamber, even through the smallest leak. Two highly sensitive CO 2 sensors measure the difference between the %CO 2 of the chamber and the atmosphere. A difference in %CO 2 of 10-12 ppm indicates a leak. The alarm is activated and the carton /tray is automatically rejected.

  • Leak Test - an overview | ScienceDirect Topics

    The helium test is a very sensitive leak test technique because of the small dimension of the helium atom and its diffusivity, its rarity in the atmosphere (5 ppm by volume) and the selectivity of detection with a mass spectrometer. The principle of the helium test for a SG is given in Fig. 15.11.

  • The 5 Best Refrigerant Leak Detectors Reviews Buying Guide

    Jul 15, 2020 · Thus, a given leak detector should be highly sensitive and able to detect small leaks as well. As a result, these refrigerant leak detectors come with a sensitivity rating like 0.25 oz/year or 0.15 oz/year. Out of these two options, the later lower rating is better since it offers higher sensitivity as it can detect much smaller refrigerant leaks.

    Pall has developed a highly sensitive integrity test system using helium as a tracer gas. The tracer gas detection method, in vacuum mode, is the method of choice recommended by USP <1207.2 1 on package integrity leak test technologies. Helium is used as a tracer gas, due to its favorable properties (inertness and small atomic size), in an inside-out test method, where helium leaking from the defects is collected in the test chamber (Figure 2).

A non-leaking standard (MASTER) is used, and is pressured at the same time as WORK. A highly sensitive differential pressure sensor detects any difference due to leaks between the change of the internal pressures of WORK and MASTER.
