1.1 MODEL 9070 OXYGEN ANALYZER DESCRIPTION
The Teledyne Analytical Instruments model 9070 oxygen/carbon dioxide Analyzer/transmitter provides an integrated
instrument for measurement of oxygen and carbon dioxide for food packaging and gas monitoring. The Analyzer
provides local indication of oxygen/carbon dioxide, plus eight other selectable variables, including minimum sample
hold level.
Two linearised 4–20 mA output signals are provided. Alarms are displayed at the Analyzer and relay contacts activate
remote alarm devices every minute.
The 9070 has a keyboard for selecting the output range, display options, alarm levels, etc. The instrument is
microprocessor based and all adjustments are made using the keyboard.
• Used for continuous gas sampling, food pack testing
• Simple to use
• Sensitive down to 0.1 ppm oxygen
• Displays 0.1% carbon dioxide resolution
• Automatic minimum/maximum sample detection, display and output to printer and 4–20 mA signals
• Automatic calibration of oxygen and carbon dioxide offset
• Linear output of % oxygen and carbon dioxide for recording or control
• Built in safety features
• 16 different alarm functions warn the operator of gas composition, sensor or Analyzer problems
• RS 232C/RS 485 printer/computer interface
1.2 DETAILED SPECIFICATIONS
Measuring Range
• 0.1 ppm to 100% oxygen
• 0 to 100 % carbon dioxide
Response Time
• Less than two seconds with a gas flow of 400 cc (50 scfm) per minute, oxygen
• Less than six seconds with a gas flow of 400 cc (50 scfm) per minute, carbon dioxide
Accuracy
• ±1% of actual measured oxygen value with a repeatability of ±0.5% of measured value.
• Carbon dioxide ±3%
Warm Up Time
• Fifteen minutes approximately for optimum accuracy. Useful readings are possible within 10 minutes after
switching the instrument on.
