Appendix C: Non-Standard Toxic Gas Sensors

Appendix C describes the Eagle’s non-standard, electrochemical toxic gas sensors. This appendix also offers information for calibrating and replacing non-standard toxic gas sensors. Non-standard electro- chemical toxic gas sensors are toxic gas sensors other than CO or H2S.

Specifications

Table 8 lists specifications for the non-standard toxic gas sensors. The alarm settings are user-adjustable (see “Updating the Alarm Point Settings” on page 32.)

Description

Non-standard toxic gas sensors are mounted in the front half of the instrument case. These sensors each include a dedicated amplifier with ZERO and SPAN controls. A bracket secures the sensor/ amplifier assembly to the instrument case. A flow adapter connected
