Since 1969 A-Vac has specialized in sales and service of all popular brands of helium leak detector and mass spectrometers as well as accessories for Veeco, Varian, Edwards, Alcatel, CEC/Dupont and many others! New and rebuilt machines are always available along with a huge stock replacement and hard to find parts. Filaments, sources, leak standards, sniffer probes, diffusion pumps, turbo pumps and replacement vacuum pumps are all in stock to keep your leak detector up and running.
Helium leak detectors, helium leak sniffers and helium mass spectrometers are instruments that are used for detecting and locating small leaks. Originally developed by the Manhattan Project, helium leak detectors find microscopic leaks for a variety of industries, including medical, automotive airbag, road wheel, vacuum systems, hermetic seal verification, etc.
A helium leak detector makes use of a vacuum chamber comprising a sealed, helium- filled container. If Helium leaks out of the container, the mass spectrometer detects the leakage as well as the rate at which the leakage occurs.
Since leak detection and prevention is a critical part in industrial, medical, aerospace and other related industries, reliability and accuracy plays a critical part while selecting the helium leak detectors or helium leak sniffers. A-VAC offers a wide range of equipment both new and rebuilt to insure reliable, repeatable, high quality testing for years to come.
