Helium Leak Detector

For highest sensitivity and greatest accuracy.

The heart of the most sensitive and accurate instrument for detecting extremely small leaks is the mass spectrometer, which is used to measure the rate of flow of a tracer gas through leaks using vacuum, pressure or vacuum-pressure techniques. The mass spectrometer detects the tracer gas and converts it to an electrical signal proportional to the size of the leak. Helium is usually used as a tracer gas because of its unique combination of properties:

  • Helium is extremely rare in the atmosphere, so there is little ambient “noise” to interfere with leak measurement
  • Non-explosive, non-toxic, completely inert (no contamination of the tested product)
  • Will not contaminate and desensitize its own detector as is common with detectors using other tracers
  • Helium is a small, light molecule (mass 4) and will flow readily through extremely small leaks

The most advanced leak-test instrumentation and application experience in the industry.
    
Highest sensitivity, fastest cycle times, one-button start-up, and fully automatic operation, tuning and calibration are hallmarks of Vacuum Instruments Corporation (VIC).  VIC’s advanced leak detectors and turnkey systems are ideal for precision, high-volume demands of industry and science.

Automotive Fuel Delivery Solutions
Solutions for automotive fuel delivery leak testing equipment. Leak testing requirements for fuel system components have been lenient (0-2 cc/sec). Amendments to the EPA Clean Air Act and the California Air Resources Board have imposed evaporative vehicle emission standards resulting in a more stringent leak test requirement. To fulfill these test requirements, VIC has developed ultra-sensitive mass spectrometer methods to leak test fuel system components, including fuel tanks, tube and flange and fuel rail assemblies.
