Oxygen Sensor for Legacy Pro O2 & C-Squared Analyzer
The D-13 oxygen replacement sensor has a three-prong plug that fits legacy Nuvair Pro O2 and C-Squared oxygen analyzers with a threaded faceplate insert. Please check the product number ("type") of your analyzer's sensor before ordering.
Be careful not to confuse the D-13 replacement sensor with the D-31 carbon monoxide (CO) replacement sensor.
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.
