• 4 user selectable output ranges to choose from: 0-1%, 0-5%,
 0-10% and 25%. Optional ranges: 0-1000ppm, 0-50% or 0-100%
 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 0.00% 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: 0-1%, 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: 0-1%, 0-5%, 0-10% and 25%
• Power requirements: 115VAC/230, 3-10watts depending on
 201R model selected
• Minimum detection: 0.01% of oxygen
• Repeatability: +/- 0.2% of range or +/- 0.1% of oxygen,
 whichever is greater
• Operating temperature range: 32 to 115˚ F
• Diurnal temperature specification:
 < +/- 3 % of scale over temperature range
• 90% full scale response times for specified range:
 0–25% <10 seconds with P-2 inert background gas sensor
 0-25% < 35 seconds with P-3 CO2 background gas sensor
 0-100% <35 seconds with P-4 100% O2 gas sensor
• Area Classification: Designed to meet General Purpose
 requirements 
• Inlet gas pressure for Model 201RS and Model 201RSM:   0.5
 to 30psig. Model 201RS is for use in a single gas stream only.
 Model 201RSM is for use in 1-5 multi gas streams with built-in
 programmable sequencer
• Inlet gas pressure for Model 201RSP and Model 201RSPM:
 atmospheric pressure. Model 201RSP is for use in a single gas
 stream drawing from atmospheric pressure. Model 201RSPM is
 for use in 1 to 5 multi gas streams with built-in programmable
 sequencer drawing from atmospheric pressures
• Expected pump life for Models 201RSP and 201RSPM: 2+ years
• Gas connections: ¼” 316 S.S. compression fittings
• Wetted parts: 316 S.S. fittings, electroless nickel plated cellblock,
 gold plated contacts, acrylic flow meter and Viton O-rings
• Unaffected by changes in flow rate from 0.1 to 2.0 SCFH
• Mounting: panel mount
• Dimensions: 9.0”W x 5.0”H x 6.5”D
• Weight: 8-10 lbs. depending on 201R model selected
