Finding Leaks in Your Vacuum Furnace – Part XI | The Ipsen

May 05, 2016 · The spray probe technique is the traditional form of leak checking; it involves pumping down the furnace, applying helium (e.g., with a helium mass spectrometer connected) and looking for a response. The sniffer probe technique, on the other hand, is for applications where it’s not feasible to evacuate what you’re testing for leaks.

The Fundamentals of High, Ultra & Extreme High Vacuum

In terms of HVs, XHVs and UHVs, it is small leaks that are the main cause of concern, and the only credible method to detect leaks smaller than 10-7 mbar.l/s is with a helium leak detector (HLD). A leak diameter-equivalent of 10 -12 mbar.l/s (which equates to 1Å) is also the diameter of a helium molecule, and is the smallest leak rate that can
