Appendix H: Infrared Methane Sensor
Overview
This appendix describes the EAGLE 2’s infrared methane sensors and includes
instructions to use an EAGLE 2 that has an infrared methane sensor installed. It also
includes instructions to replace an infrared methane sensor.

Target Gases
The infrared methane sensor is setup for and factory-calibrated to methane. There are
gases that the sensor will still detect and respond to. There are also gases that the methane
sensor will not detect or respond to. Lists of the gases falling in each of these respective
categories can be found below. Consult RKI Instruments, Inc. for combustible gases not
listed below.
The infrared methane sensor is known to respond to the following combustible gases:
•
ethane
•
hexane
•
IPA
•
isobutane
•
MEK
•
propane
•
styrene
•
toluene
The infrared methane sensor is known to
not
or to poorly respond to the following
combustible gases:
