Product Specifications
  • Convenient and Portable
    Ergonomic handheld gas purity analysers equipped with Analytical Industries Inc. sensors are highly practical thanks to their compact size and light weight. They can be used with internal or external sensors depending on the application requirements.

  • Advanced Technology "AII" Sensors
    Analytical Industries Inc. oxygen sensors are designed to avoid potential weaknesses found in typical galvanic cell designs. All materials and component assembly processes used in these sensors that deliver superior performance are the result of in-house R&D at AII. They do not require frequent maintenance.

  • Long Operating Life
    Measuring 0-100%vol, these instruments feature an extended sensor life and very long battery operating life using readily available 2xAA batteries. The devices provide an operating life exceeding 1,300 hours in continuous operation.

  • Application Areas
    Portable oxygen analysers have a wide range of application areas, notably weld purge gas quality measurements, personal safety, dive cylinder breathing mixture measurements (pure oxygen or nitrogen blends), and dive cylinder carbon monoxide checks.

  • AII-3000 Options
    - The AII-3000 series offers 4 distinct options comprising alarmed/non-alarmed and internal/external sensor configurations. Two alkaline batteries provide up to 50 days of continuous use.
    - AII-3000-A – External sensor, non-alarmed
    - AII-3000-AHC – Internal sensor, non-alarmed
    - AII-3000-M – External sensor, with alarms
    - AII-3000-MHC – Internal sensor, with alarms

    Measurement and Standards Approach
    In process gas analysis, as much as the measuring range, sample gas pressure, flow rate, background gas, moisture/condensation risk, sensor material, and calibration gas are also critical selection parameters. The AII-3000 is a general-purpose analyser with no hazardous-area classification or signal output. M/MHC variants have adjustable high and low alarm levels.
