Safety Rating: This intrinsic safety rating permits its deployment in all potentially explosive
atmospheres of the quoted (or less demanding) rating. That is, in areas where explosive gases (of
Group IIA, IIB and IIC) are intermittently present (Zone 1), within an ambient temperature range of 20°C and +60°C.
GasCheck complies with the requirements of 73/23 EEC low voltage directive and, apart from a low
voltage pump, there are no moving parts within the instrument so that the machinery directives are not
applicable.

Statements
Responsibility for Use
Inadequate performance of the gas detection equipment described in this manual may not necessarily be
self-evident and consequently equipment must be regularly inspected and maintained. Ion Science
recommends that personnel responsible for equipment use institute a regime of regular checks to ensure it
performs within calibration limits, and that a record be maintained which logs calibration check data. The
equipment should be used in accordance with this manual, and in compliance with local safety standards.
Legal Notice
Whilst every attempt is made to ensure the accuracy of the information contained in this manual, Ion Science
accepts no liability for errors or omissions, or any consequences deriving from the use of information
contained herein. It is provided "as is" and without any representation, term, condition or warranty of any

Introduction
Scope and definitions
This manual provides installation, operation and maintenance instructions for the GasCheck 3000 and
3000is. You must use the GasCheck as specified in this manual.
Read this manual before you install and operate the GasCheck. Important safety information is highlighted
as WARNING and CAUTION instructions; you must obey these instructions. The use of WARNINGS and
CAUTIONS is defined below.
The units of measurement used throughout this manual conform to the SI international system of units of
measurement
Description
Refer to Figure 1. The GasCheck is a portable, battery-powered, hand-held gas leak detector. Indications of
a leak are shown on the digital display (2) and are also given by a front panel mounted LED flasher (3) and
as audible clicks from the rear panel loud speaker (6). Two versions of GasCheck 3000 are available:
• The standard GasCheck 3000 - suitable for leak detection of all non-flammable gases other than air.
• The GasCheck 3000is - intrinsically safe and is suitable for leak detection of hydrogen and other
flammable gases, and for leak detection in hazardous areas of Ex ia IIC T4 rating.
The GasCheck has a convenient storage and carrying case, together with a spare battery holder, a long
flexible probe (for leak detection in areas where access is restricted) and a box-spanner for probe changing.
Principal of operation
When the GasCheck is switched on, a small internal fan draws gas samples through the probe and into the
GasCheck. The GasCheck measures the thermal conductivity of the gas samples.
When you first switch on the GasCheck (or when you press the manual zero key: see Section 4.1), an auto
zero is made. If further samples have a different thermal conductivity from the zeroed sample, the Gas
Check calculates and displays the difference as a leak rate.
This means that you can use the GasCheck to detect any gas other than that in which the Gas Check is
zeroed.
WARNING
Warnings are given where failure to observe the instruction could result in
injury or death to people.
CAUTION
Cautions are given where failure to observe the instruction could result in
damage to the equipment, associated equipment and process.

Introduction
Applications
You can use the GasCheck on many types of applications, including those listed below.
• Quality assurance testing on manufactured component seals.
• Laboratory applications, such as the detection of leaks from gas chromatographs, from mass
spectrometers, from gas cylinders and fittings.
• Industrial applications, such as the detection of leaks from gas installations, in cylinder receiving
rooms, from pipeline assemblies, the detection of leaks from stored gases and the detection of
vapours released from stored chemicals.
• Medical applications, such as the detection of leaks from anaesthetic gas bottles and pipelines and
leak testing of membrane materials, glove boxes and so forth.
• Valve emission evaluation to EPA (Environmental Protection Agency) method 2.1
• Leak testing of pipeline joints, gaskets, chamber windows and so forth
