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
