1 INTRODUCTION
GAZOMAT™ has extended its range of laser spectroscopy based (Tunable diode Laser Absorption
Spectroscopy – TDLAS) gas detector with the GAZOSCAN™ detector.
GAZOSCAN™ is an ultra-light and highly sensitive handheld remote methane leak detector
(RMLD) which uses infrared lasers to remotely detect methane leaks. A smart sensor using infrared
(TDLAS) technology guarantees measurement efficiency.
GAZOSCAN™ comes with Bluetooth capability that can transfer measurement data in real-time to
a dedicated APP supplied on option. Users can use the APP to check, record and export the data.
Key features of a device with highly intuitive handling
 Methane selectivity
 Excellent detection at 100 meters (328 feet)
 Detects through glass
 5 ppm sensitivity per meter
 Fast response time, 0.1s
 Lightweight, 0.76kg (1.68lbs) with battery
 Visual and audio alarms with configurable alarm threshold
 Large color 2.8in LCD screen
 Bluetooth® data transmission
 Green guide laser light
 Red dot sight for precise targeting in bright sunlight or ambient light
Purpose
Ultralight, compact and easy to use, the GAZOSCAN™ device is designed for rapidly inspecting
difficult-to-access installations and equipment in industrial sites. The GAZOSCAN™ is suited to
any situation where field technicians cannot operate close to the inspection zone:
 Because it is not accessible – overhead installations…
 Or for safety reasons.
IECEx and ATEX certified, it can be used in explosive atmospheres in confined and unconfined
areas.
Areas of application
The GAZOSCAN™ meets the safety and performance requirements of a large range of applications
including but not limited to:
1. Natural gas transmission and distribution pipeline leak inspection (inspection on street,
between buildings, inspection of overhead pipelines, valves, service galleries of bridges...)
2. Inspection of buildings (entrances, staircases, through windows) and fenced residential
properties
3. Safety of first responders’ interventions
4. Industrial site monitoring (refineries, natural gas production, processing and storage plants,
compression stations, injection/extraction wells…).

8 SELF-TEST, RED DOT SIGHT AND BLUETOOTH
Initialization /Self-test
The GAZOSCAN™ automatically performs a Self-Check when powered on. The initialization
Self-Check is performing a series of internal diagnostics to verify the integrity and performance of
the sensor and components. The device will continue to the subsequent user screens upon a
successful result of the diagnostics analysis. If any errors are found during the Self-Check, an error
screen will occur. In this case, contact your local GAZOMAT™ service center for assistance.
Instructions on the red dot sight
Users can look through the red dot sight to achieve better aiming. The red dot sight is powered by
the device. It automatically lights up after powering on the device.
NOTE: The sight is effective when aiming over 15m away. If the distance from the measured object
is too short, the red dot will not overlap with the green indication laser.
Red dot sight diagram
If the red dot and the green indicator laser do not overlap when aiming for a long distance (>15m),
the red dot calibration can be performed by adjusting the knob on the sight.
If the red dot is higher than the green
indication laser, turn the knob
counterclockwise to make it lower.
If the red dot is lower than the green indication
laser, turn the knob clockwise to move it up.
If the red dot is to the right of the green indication laser,
turn the knob counterclockwise to shift it to the left;
If the red dote is to the left of the green indication laser,
turn the knob clockwise to shift it to the right.

V5.00 07/03/2019 © GAZOMAT™ 19/28
10 TECHNICAL PRINCIPLES – DO’s and DON’TS
Working principle
For the GAZOSCAN™ to detect a leak is the result of a laser beam passing through a gas plume
and reflecting off a surface.
The reflected light is collected by the GAZOSCAN™ and converted into a methane concentration.
PPM*M measurement unit
ppm*m is the Parts Per Million concentration that a gas plume 1 meter in depth would have.
 Therefor a 1-meter plume of methane at a concentration of 5000 ppm would be read as 5000
ppm*m.
 While a gas plume that was 0.5 meter in depth with the same concentration of 5000 ppm would
be read as 2500 ppm*m.
 In the case of a 2-meter plume of methane at the same concentration of 5000 ppm, the reading
will be 10000 ppm*m.
 The GAZOSCAN™ emits an
infrared laser at 1.65 um.
 The laser beam travels to the
target, is partially absorbed by
the gas, then reflected all the way
back into the receiver.
 The reflected laser is collected
and converted to an electrical
signal that carries information
needed to deduce the relative
methane concentration.
 The reading is expressed by a
methane column density
(ppm*m). it is the integral of the
methane concentration (ppm)
and the distance (m) on the
optical path.

GAZOSCAN™ – Operating Manual
V5.00 07/03/2019 © GAZOMAT™ 20/28
Detection Do’s and Don’ts
10.3.1 Case 1 – Detection through glass
When detecting through the glass, if the infrared laser is incident on the glass vertically, part of the
light reflected by the glass will be received by the device, which will cause the light intensity
saturation or inaccurate measurement result. In such case, the GAZOSCAN™ needs to be pointed
as shown in figure below to avoid receiving the light reflected by the glass.
A B
Case 1: Detecting through glass
10.3.2 Case 2 – Detection through materials with strong absorption or reflection effect on the
infrared laser
Avoid detecting through materials that have strong absorption or reflection effects on the infrared
laser, such as PMMA, laminated glass or anti-infrared glass.
In such case, the methane concentration behind can’t be detected or the measurement result may be
inaccurate.
Case 2: Avoid detecting through anti-infrared or absorbing infrared material
