Pro CO2 Alarm Analyzer - Panel Mount

Designed for installation on a control panel or other flat surface, the Nuvair Pro CO2 panel mount alarm analyzer measures carbon dioxide levels in breathing gas mixtures, in air, or it can be connected in-line on your high- or low-pressure compressor for continuous monitoring of CO2 contamination. Comes equipped with two custom audible and visual alarms for low and high set points.


The Nuvair Pro CO2 panel mount alarm analyzers comes in three power options: Rechargeable lithium battery (SKU 9617-LB), wall plug-in model (SKU 9617-E) or DIN powered for hard-wiring to your compressor (SKU 9617-DP). The CO2 sensor is auto-calibrating and provides a temperature-compensated, linear CO2 measurement over sensing range.

Two audible and visual alarms for low and high carbon dioxide content can be set by the user. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds remote alarms, or activates emergency backup systems.

PLEASE NOTE: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator may be required.
