AMI Model 111 series of portable percent oxygen analyzers provide unmatched performance in a compact, durable, comprehensive package.

It is supplied standard with state-of-the-art microprocessor based electronics and employs a revolutionary long life zirconium oxide sensor that provides unprecedented stability and accuracy throughout its measurement range. The model 111 is so stable it requires only a bi-annual calibration and the sensor lasts up to 10 years when used continuously for measurements in the range of 0-21% oxygen and longer if used intermittently. This eliminates the need to purchase, stock, frequently calibrate or replace the standard galvanic type oxygen sensors, greatly reducing overall costs

The 111 series is available with one of the following single measurement ranges: 0-25%, 0-50% and 0-95% as well as standard features listed below.

  • Data logger. Logs data for 15 days @ 1min intervals.
  • High-resolution single range LCD rapidly reads from .01ppm to 25% (or other standard range) without LCD range changing delays or the need for manual range switch adjustments.
  • 10-year life sensor: requires no support or calibration gases (other than ambient air) for its annual calibration (25% range only).
  • Battery charger: 100/220VAC, 10Watts
  • User Interface C/D and Cable: used for retrieving logged data and automatically graphs and time stamps downloaded data.
