Sensors & Batteries

We stock carbon monoxide (CO) and oxygen (O2) sensors and batteries for all our current and legacy gas analyzers, such as the Pro O2, Pro CO, Pro Trimix, 4 Warn, and O2 Quickstick. We also carry replacement sensors for DE-OX, UBS and OMS analyzers.

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.
