1.1 GENERAL
The HeliTest is a self contained, ready to use portable
leak detector able to detect, in fully automatic,
autoranging mode, a helium concentration as small as
2 parts per million (ppm).
The leak value is displayed on an LCD alphanumeric
display, and an audio signal proportional to Helium
concentration is provided.
It incorporates all facilities required for self-diagnostic
and protection features, and all controls are on the front
panel.
The operator can hang the entire unit over the shoulder
and will search for leaks using the extension probe.
