Agilent G3388A Leak Detector
Operation Manual

1
Introduction

The Agilent Technologies Leak Detector is a portable, highly 
sensitive instrument designed to detect helium gas leaks in gas 
chromatographs (GCs) and their accessories, such as purge and 
trap systems. The detector indicates leaks through a dual 
system that consists of an indicating LCD and an audible alarm. 
The detector is more reliable and convenient to use than soap 
solutions and is capable of detecting even the smallest, hard-to- 
reach gas leaks.
