Handheld Hydrogen Leak Detector Introduction

Introduction
1.1 Overview
The Model 2240 Hydrogen Analyzer is a handheld portable leak
detector for sensing hydrogen gas in air. It employs two sensing
elements on the same semiconductor die and can detect hydrogen leaks
as low as 15 parts per million (ppm). It will not saturate or be destroyed
when detecting hydrogen concentration up to 100%. It is battery
powered and will operate for over 10 hours on a single charge. The
included battery charger will recharge the internal lithium-ion battery in
4 hours.
As the operator moves a hydrogen probe over the area of interest, it
senses the presence of hydrogen. Indicators in the probe tip alert the user
to the presence of hydrogen and the concentration is displayed on the
control unit display. The probe attaches to the controller with an
extendable coiled cord that allows up to 47 inches of reach from the
Controller. The thin probe and flexible cable allow sensing in areas
inaccessible to most other tools.
1.2 Typical Applications
The Model 2240 analyzer is a versatile, lightweight instrument that
can be brought to a process area for analysis. Typical applications for
the analyzer include:
• Leak checking process lines for H
