AII-2000A Oxygen Analyzer

The AII-2000A is an FDA-approved handheld oxygen analyzer from Analytical Industries, created to be accessible and easy to use for medical professionals. The AII-2000A operates with advanced galvanic oxygen sensors designed to last long and handheld. It features spot-checking oxygen levels for anesthesia, intensive care, and oxygen therapy.

Application Considerations:

• Anesthetic agents:  Complies with  ISO  80601-2-55 for  the maximum error allowable over a given duration.
• Temperature: Signal output and expected life change 2.54% per 1°C. Signal output is compensated within following ambi- ent calibration, step changes of 15°C require 30-60 minutes to equilibrate.
• Pressure: Signal output and expected life change proportional- ly. Accurate at any pressure provided it is constant, change is gradual simulating the human lung and the device is calibrat- ed at the pressure of the sample gas.
• Humidity: Non-condensing RH has no effect. Adding water vapor to the sample reduces the oxygen concentration.
• Condensation: Causes erroneously readings if allowed to cover the sensing area or collect on electrical connections.
• Electromagnetic Radiation: Susceptible to interference over frequencies from 26 MHz to 1000 MHz.
