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.

  • 0-100% O2 measurement range
  • Long sensor life up to 60 months (AII-3000)
  • Battery life up to 13,000 hours of continuous use (Palm O2)
  • Integrated or remote sensors
  • Fast response time of T90 in <10 seconds
