The Palm O2, Palm CO and AII-300 are handheld oxygen analyzers that provide a very easy way to verify oxygen levels prior to welding or in scuba diving tanks.

Analytical Industries’ AII-3000 series or Palm O2 are a convenient way to check oxygen levels in welding gases. These cost-effective gas analyzers also measure and display the concentration of oxygen in compressed breathing air tanks intended for scuba diving, for personnel safety, O2 deficiency in confined spaces, as well as confirming the O2 levels prior to welding. These monitors use similar electrochemical galvanic fuel cell oxygen sensor that are extensively used to measure concentrations from 0% to 100% O2 in gas streams.
