Oxygen Sensor Replacement | 9507


The Nuvair 9507 replacement oxygen sensor is for use with the DE-OX ZIP PRO oxygen analyzer. Optional diverter available for purchase.


The Nuvair 9507 is a replacement electrochemical oxygen sensor for gas analyzers. Under normal use, oxygen sensors have an expected service life of 36 months. The 9507 replacement sensor fits the DE-OX ZIP PRO gas analyzer.

Optional diverter available for purchase (SKU DIVERTER, now black in color).

WARNING: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. 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. A faulty Flow Restrictor can lead to a false analyzer reading. Flow Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to serious personal injury or death.
