2.2 Special conditions for safe use
2.2.1 Intrinsic Safety (Ex protection)
IRwin is certified intrinsically safe to prevent ignition of flammable atmospheres.
IRwin holds an ATEX certificate for EU and corresponding certificates for several other
regions as shown by the attached certificates, see Certificates [}98]).
For details of rating, see EX certification (intrinsic safety) [}24].
The "X" after the respective type certificate number relates to the following special
conditions for safe use:
The only device allowed to be connected to the charging socket on any of the models
• IRwin SX
• IRwin SXT
• IRwin SXG
• IRwin SXGT
is the Ex Certified IRwin Charging adapter (PN 580-604).
The charger or car adapter is subsequently connected to the inlet of the Ex Certified
IRwin Charging Adapter.
This means that the charger for IRwin S must, under no circumstances, be connected
directly to the charging socket on any of IRwin models SX, SXT, SXG, and SXGT. See
also Charging the battery [}35].
IRwin SXnn is certified as intrinsically safe at an ambient temperature of -20 - +50°C.
Further temperature restrictions apply to oxygen and toxic gas measurment of IRwin
SXT and SXGT. See Certified Gas Measurement.
IRwin SXnn is certified for use in Gas groups IIA, IIB and IIC and in Zones 0, 1 and 2.
The external surface of the enclosure is therefore slightly conductive to prevent
electrostatic charging and sparks. Labels added for marking purposes must not be
larger than 400 mm2. If larger the instrument should not be used in gas group IIC,
Zone 0 applications. Natural gas applications are not affected by this regulation.

Operation mode and
Ex
The safety related modes Ex and Ex Tox has certified safety features. The detector
monitors its functionality and proper function is indicated by an acoustic alive signal
beeping every 20 s and by the LED being green. This requires that the leak detector is
calibrated according to the instructions and intervals stated in this manual.
If the signal LED is red, this indicates an alarm or an error.
Green LED and short beep every 20 s: Function OK.
Red LED: Gas alarm or instrument error.
Yellow LED: Special state Special state indicates functioning system but alarms are
typically not active. This special state may occur for example during calibration or
when changing a setting in the leak detector.
IRwin Methane Leak Detector was built according to the state-of-the-art and the
recognized safety regulations. Nevertheless, improper use may result in risk to life and
limb on the part of the user or third parties, or damage to the leak detector or other

4 Description
4.1 Function
The IRwin is a portable methane leak detector for gas pipeline survey. It measures
following gases depending on the leak detector version:
• Methane
• Carbon dioxide
• Ethane
• Propane
• Butane
• Oxygen
• Hydrogen sulfide
• Carbon monoxide
There are several probes available for the leak detector:
• The carpet probe is used for surveying paved or smooth surfaces. Pull or push the
carpet along the surface.
• Use the bell probe for measuring gas at specific points. Press the bell firmly down
to pull gas through the surface.
• The hand probe is used for checking features on or in buildings. The hand probe
also constitutes the handle for the carpet probe and bell probe.
• The Bar Hole probe is used to sample air from drilled holes. Push into hole and
tighten screw to expand rubber before connecting sample line.
• The optional Hand Probe Flexible Extension can be connected to the hand probe
or rod for easier access.
• The Swan Neck Probe is used on uneven surfaces and in bushes etc.
• The Flexi Bell is used for simple survey including meters and piping. The bell
adapts to pipe geometry.
INFICON single-cell
wide range technology
(patent pending)
IRwin methane leak detector uses the unique INFICON single-cell wide range
technology for detecting all concentrations from 1 ppm to 100 Vol% methane. This
technology is very sensitive to the ethane content of natural gas. Therefore, large
deviations can occur at higher methane concentrations if the ethane concentration is
not compensated for. The instrument has built-in routines for ethane compensation.
The actual ethane concentration can be determined using the IR Ethane Analysis
function. This can be used to automatically set the compensation concentration. If
preferred you can instead set the ethane content manually. The safety certified modes
Ex and Ex Tox are not affected by this phenomenon. See "IR Ethane Analysis and
compensation [}76]".

INFICON Description | 4
IRwin-Operating-instructions-mina66en1-15-(1904) 15 / 128
IRwin SXG and SXGT models also have GC Ethane Analysis capability for
distinguishing between Natural gas (NG), liquid petroleum gas (LPG) and swamp gas
by determining the presence of methane, ethane and propane in the sampled gas.
The GC Ethane Analysis function is not affecting the ethane compensation.

WARNING
Risk of explosion due to not approved probe parts.
The original INFICON Hand probe is the only part of the probe system that is certified
for use in potentially explosive areas. Other parts of the probe system, or third party
accessories are not allowed in potentially explosive areas.
► Pay proper attention to safety when using other accessories for locating and
pinpointing gas leaks in none classified areas.
Carpet probe When you are looking for gas leaks on paved surfaces, use the Carpet probe. Pull or
push the Carpet probe along the surface.
Fig.2: Carpet probe
Bell probe When searching for or measuring gas leaks at particular spots, use the Bell probe.
This can be used to pull gas through most pavings. It is also suitable for emergency
testing if surface is wet.
