Oxygen Sensor Replacement | 9507


The Nuvair 9507 replacement oxygen sensor is for use with the Nuvair Pro O2 Alarm Panel Mount (SKU 9612-B-R) and the DE-OX ZIP PRO (SKU 9631) oxygen analyzer. Optional diverter available for purchase (SKU 9507-D).


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 Nuvair Pro O2 Alarm Panel Mount (SKU 9612-B-R) and the DE-OX ZIP PRO (SKU 9631). Optional diverter (SKU DIVERTERS) available for purchase with this sensor (SKU 9507-D).

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.
