Nitrox Analysers for Welding

AII-3000 Series, Palm O2

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.
