Restek Electronic Leak Detector
Operating Instructions

1.0 Introduction

Restek's portable electronic leak detector is specifically designed for use with gas chromatography (GC) sys-
tems. It detects small leaks of any gas with a thermal conductivity different from air. The reference gas inlet
(Figure 1) draws in ambient air for comparison to gas drawn into the sample probe. The intensity of a leak is
indicated by both an LED light display and an audible alarm. The following table explains how to interpret the
LED display.
NOTE: The leak detector is not a quantitative device, it is a qualitative measure of the location, intensity, and
nature of a gas leak.
It is best practice to use a leak detector daily to check critical seals (for example, septa, column nuts, reduc-
ing nuts, and fittings on gas lines). In addition to being used regularly, the leak detector should be charged
regularly to ensure the battery pack continues to hold its charge.
If this instrument is used in any manner other than described in the manual, the CE declaration is void.
The leak detector is manufactured by Restek and is backed by our 100% satisfaction guarantee.
