Analytical Industries Nitrox Analysers for Welding

 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.

AII-3000

With four format options, these handhelds give user the flexibility to match the instrument to their needs with four combinations of alarms, no alarms, internal and external sensors. 2 AA batteries give up to 50 days of use.

• AII-3000-A – External sensor, no alarm
• AII-3000-AHC – Internal sensor, no alarm
• AII-3000-M – External sensor, alarm
• AII-3000-MHC – Internal sensor, alarm

Palm O2 and Palm CO

With only two buttons, and one-touch calibration, they are very simple to use. This is the ideal cost-effective choice to check for O2 or CO in your scuba tanks. Palm O2 is available with internal or external sensor and offers excellent battery life of up to 18 months of use.
