• 10 user selectable output ranges to choose from:
 0-10ppm, 0-50ppm, 0-100ppm, 0-500ppm, 0-1000ppm,
 0-.500%, 0-1%, 0-5%, 0-10% and 25%
 The user selection of an output range simultaneously
 controls the two alarms, the analog output and the data
 logger so that all 4 functions operate on the same range
• Digital display: High resolution 3 ½ digit LCD. Reads full
 scale from 0.00ppm to 25.0% independently of output
 range selection
• Alarms: 2 fully adjustable oxygen concentration alarms
 Dry contacts 5A. @24VDC/115VAC
• Alarm delays: Programmable from 0-300 minutes
• Alarm hold off: Programmable from 0-120 minutes
• Isolated analog output signal: 1-5VDC or 4-20mA
 Represents the output range selected: 0-10ppm, 0-50ppm,
 0-100ppm, 0-500ppm, 0-1000ppm, 0-.500%, 0-1%, 0-5%,
 0-10% and 25%
• Data logger: Logs data for 15 days @ 1 minute intervals,
 30 days @ 2 minute intervals, etc. Represents the output
 range selected: 0-10ppm, 0-50ppm, 0-100ppm, 0-500ppm,
 0-1000ppm, 0-.500%, 0-1%, 0-5%, 0-10% and 25%

 12VDC non heated; <24W @12VDC with heated option
• Minimum detection: 50ppb of oxygen
• Repeatability: +/- 1% of range or +/- 0.2ppm of oxygen,
 whichever is greater
• Operating temperature range:
 25 to 115˚ F non-heated; -20 to 115˚ F heated option
• Diurnal temperature specification:
 < +/- 3 % of scale over temperature range
