Operating instructions

1.0 Introduction

The Thermo Scientific
chromatography (GC) systems. It detects minute leaks of any gas with a thermal
conductivity different from air. The reference gas inlet (Figure 1) draws in ambient air for
comparison to air drawn into the sample probe. A leak is indicated by both an LED light
display and an audible alarm.
If this instrument is used in any manner other than described in the manual, the CE
declaration is void.
