Our Helium Leak Test Gas Systems automatically generate a continuous supply and precise mixture of helium tracer gas for leak testing completed products or components. These systems cover a wide range of applications, required test gas pressures, and fill volumes. Nine models are divided evenly among systems rated to deliver 150 psig, 300 psig, or up to 3000 psig of test gas. Volume capacity at these test pressures range from 10 scfm to 45 scfm. Helium mixture is accurately managed to ±.1% by a gas analyzer. An on board automated regenerative gas drying system ensures test gas is dry to -40° F dew point.
