Page 4: Preface
Every effort is made to ensure that AMI products provide reliable, effective performance. However there are many pitfalls in achieving correct oxygen analysis, particularly at low ppm levels, and AMI stands ready to provide a complete solution to the analysis problem, from sample system design to on-site troubleshooting and problem analysis. -
Page 5: The Ami Oxygen Probe Analyzer
• Oxygen sensor: AMI uses an industry standard electrochemical sensor. This measures the concentration of oxygen in a gas stream, using an oxygen specific chemistry. It generates an output current in proportion to the amount of oxygen present, and has zero output in the absence of oxygen, thus avoiding any requirement to zero the analyzer. -
Page 6: Sensor Warranty
The sensor is warranted to operate for a period determined by its class. If the sensor ceases to operate correctly before this time has elapsed, contact AMI for a return authorization for evaluation. If there is any evidence of defective material or workmanship the sensor will be replaced free of charge. -

The output of the sensor will vary by about +/- 20% between units, in other words air will make the output come to somewhere between about and on a nominally output unit. The following section is intended to provide tips on performing calibration. AMI Analyzer Manual • • • • 10... - Page 12 3. If the sensor chosen has a time constant of 13 seconds, the calibration routine should allow at least 65 seconds for the reading to stabilize. 4. If the system performs an automatic calibration, some means of alerting the user to calibration failure must be made. AMI Analyzer Manual • • • • 11...

Page 13: Maintenance And Troubleshooting
Maintenance and troubleshooting Maintenance: The AMI oxygen probe is virtually maintenance free other than for periodic calibration and occasional sensor replacement. Sensor Replacement: This should be done on a regular schedule, rather than as a response to a dead sensor. See the chart below for recommended sensor replacement. -
Page 14: Sensor Replacement Cautions
Sensors usually contain lead which is toxic, and should generally not be thrown into ordinary trash. Refer to the MSDS to learn about potential hazards and corrective actions in case of any accident. Figure 4. Inserting sensor in probe AMI Analyzer Manual • • • • 13... -

Page 18: Disclaimer
The AMI analyzer is not designed as a primary safety device, that is to say it is not to be used as the primary means of assuring personnel safety. In particular it is not designed to act as a medical instrument, monitoring breathing air for correct oxygen concentration, and should not be used as such when it is the only safety device on the gas system. -

The contents of the sensor are not flammable. There are no fire or explosion hazards associated with the sensor. Potential for reactivity: The sensor is stable under normal conditions of use. Avoid contact between the sensor electrolyte and strong acids and oxidizing agents. AMI Analyzer Manual • • • • 18... -
