When the remote analysis of oxygen (O2) is required, the Nuvair Pro O2 Handheld Remote is the perfect choice. It's threaded oxygen sensor is ideal for in-line gas sampling or monitoring of contained spaces. Used in a variety of industries including diving, inerting, welding, medical, and laboratories.

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.
