Condition 1: The thermal resistance of the Gas Sensing Heads do not exceed 25K/W. This shall be taken into
account when considering its surface temperature and the temperature classification of the equipment into
which it is to be incorporated. Tests indicated that an internal ignition increases the temperature of the mesh
by further 4.2K (including a 1.2 safety factor).
Condition 2: The Gas Sensing Heads shall be protected from impact in service. The Gas Sensing Head shall be
mounted in a protective enclosure such that an impact of 7 J in accordance with IEC 60079-0:2007 clause 26.4.2
from any direction shall not cause the impact head to make contact with the Sensing Head.
Condition 3: The Gas Sensing Heads are dust-proof (IP5X) but offers no protection against the ingress of water.
Where protection in excess of IP50 is required, then the apparatus into which the Gas Sensing Head is installed
shall provide the necessary ingress protection (for example by fitting an external semi-permeable membrane).

TYPICAL PERFORMANCE DATA
(All Data are related to a calibrated sensor and conditions: Temperature 20oC, Relative Humidity 10%RH, Pressure 101kPa, 500 to 1000
ml/min Gas Flow, Averaging of 13 values, unless otherwise stated.)
11. Do not use in acid environment or operate under gases
containing acid vapours or particles.
12. Do not custom modify the sensor.
This device has been designed to be used as component
together with instruments to detect flammable gas of
13. Do not clean the sensor with acid.
14. Recalibrating the sensor will only void the
calibration certificate not the warranty.
WARRANTY & WARNING
The WARRANTY for all the INIR Gas Sensors is 2 years
from the purchased date based on use according to this
document and the INIR Application Note.
Warranty period or any extended warranties would
be confirmed with the order confirmation.
The warranty is invalidated if the sensor is used under
conditions other than those specified in this datasheet.
In addition, please pay attention to the following
conditions as they will void immediately the WARRANTY:
1. Do not allow water condensing into the sensor or deep
the sensor into water.
2. Do not vandalize the sensor.
3. Do not change label or cover it with other stickers.
4. Do not over voltage or overcurrent the sensor; always
observe the correct polarity of the input.
5. Do not solder directly onto the pins, pads or the
external body of the sensor.
6. Do not drop on the floor or hit it with tools.
7. Do not open, cut or break sensor apart.
8. Do not expose the sensor to high levels of dust.
9. Do not expose the sensor to corrosive gases or operate
under corrosive environments.
10. Do not paint or mark the sensor externally.
ESD (Electrostatic Discharge) sensitive device. Charged
devices and circuit boards can discharge without detection.
Although this product features patented or proprietary
subjected circuitry, damage may occur on devices subjected
to high energy ESD. Therefore, proper ESD precautions
should be taken to avoid performance degradation or loss
Warning! Plugging or Unplugging the Sensor while in
operation may damage the device beyond repair.
Always power down the instrument when
A. Do not drop the Integrated IR on the floor as this could
cause damage to the pins or internal components.
B. Avoid mechanical force against pins or sockets. Protect
from dust and sprayed acidic particles .
C. Do not immerse in water or other fluids.
D. Do not solder the module directly onto a pcb or
to wires. Excessive heat could cause damage.
