It uses a vacuum chamber where a sealed container filled with helium is placed. Helium leaks out of the container, and the rate of the leak is detected by a mass spectrometer. This acts as a tracer. Residual Leaks A residual leak is a real leak that may be gross, or small, according to the sensitivity setting of the leak detector. Virtual Leaks A virtual leak is the semblance of a leak in a vacuum system caused by slow release of trapped gases, as gases may adhere as pockets to the interior sides of a chamber. This can cause confusion to the operator as it may be a false indication of a present leak. A helium leak detector can be connected, and raising the helium level to 100%. If the part is small the vacuum system included in the leak testing instrument will be able to reach low enough pressure to allow for mass spectrometer operation. CoxMHP has the utilities to check tube assembly thoroughly for leaks. We ultimately utilize every aspect of Helium Mass Spec Technology to get the desired results of leak free brazed tube joints. <a href="https://limepi.wufoo.com/forms/x7w3x7/" title="html form">Fill out my Wufoo form!</a> Contract Manufacturer for Aerospace, Military, Commercial, Medical and Automotive Markets About Us AS 9100 Services Specialties Materials Aluminum Brass Copper Mild Steel Stainless Steel Tool Steel Contract Manufacturer Custom Assembly Jigs Aluminum Part Handling Carts CoxMHP CoxMHP is a full-service AS9100 Machine shop that specializes in precision engineered manufacturing.
