Description
Nitrox Analysers for Welding by 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 sensors that are extensively used to measure concentrations from 0% to 100% O2 in gas streams.
Nitrox Analysers for Welding Features
- 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
Applications
- Weld purge gas quality
- Personnel safety protection
- Checking concentrations of oxygen in scuba tanks or nitrox mixtures
- Checking for carbon monoxide in scuba tanks
AII-3000
With four format options, these handhelds give users 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.
