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. Argon is usually used as a tracer gas because of its unique combination of properties:
Argon 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.
Automated high speed production console Argon gas leak detector. Ideal for applications requiring Argon tracer gas, for products already back-filled with Argon, or for test areas with a helium high background
Gas booster systems produce high-pressure process gas supplies from lower pressure sources, typically boosting a shop air source. Base units provide up to 600 psig pressure output. Options include higher pressure outputs and process gas drying capabilities. Can be configured for single gas or dual gas boosting.
The OM Series gas calibrator leaks utilize a precision tapered glass capillary as the leak element. Gases pass through a single orifice, with the leak rate dependent upon size and gas pressure. To prevent clogging of the fine orifice, a unique particle trap is located between the capillary tube and outlet fitting.
