• 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:
 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%
• Power requirements:
 115VAC/230, 3-10watts depending on
 2001R model selected
• Minimum detection: 
 50ppb of oxygen
• Repeatability: 
 +/- 1% of range or +/- 0.2ppm of oxygen,
 whichever is greater
• Operating temperature range: 
 32 to 115˚ F
• Diurnal temperature specification:
 < +/- 3 % of scale over temperature range
• 90% upscale response times: 
 10ppm – 25% <10 seconds;
 0-10ppm < 25 seconds. Typical downscale response: 1 minute
 exposure to air down to 10ppm: < 15 minutes
• Area Classification:
 Designed to meet General Purpose requirements
• Inlet gas pressure for Model 2001RS and Model 2001RSM:
 0.5 to 30psig. Model 2001RS is for use in a single gas stream
 only. Model 2001RSM is for use in 1-5 multi gas streams with
 built-in programmable sequencer
• Inlet gas pressure for Model 2001RSP and Model 2001RSPM:
 atmospheric pressure. Model 2001RSP is for use in a single gas
 stream drawing from atmospheric pressure. Model 2001RSPM
 is for use 1-5 multi gas streams with built-in programmable
 sequencer drawing from atmospheric pressures
