Remote Oxygen Sensor Replacement | 9506

The Nuvair 9506 remote, inline replacement oxygen sensor is for use with the Nuvair Pro O2 Remote - Handheld (SKU 9452) and Nuvair Pro O2 Remote - Panel Mount (SKU 9460) oxygen analyzers.


The Nuvair 9506 is a remote, inline replacement electrochemical oxygen sensor for gas analyzers. Under normal use, oxygen sensors have an expected service life of 36 months. The 9506 replacement sensor fits the following analyzers:

  • Nuvair Pro O2 Remote - Handheld (SKU 9452)
  • Nuvair Pro O2 Remote - Panel Mount (SKU 9460)

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.
