SKC Inc PCXR8 Personal Air Sampling Pump

Universal XR Pump Model PCXR8 (5 to 5000 ml/min)
Includes the features of PCXR4 with key programmability of delay start, sample time, and intermittent sampling. Now with NiMH battery

Enhanced with programmability!

  • Built-in high-accuracy timer
    - Sample duration readout and convenient hold feature
  • Automatic fault shutdown/time retention
  • Ensures sample integrity upon low battery or excess back pressure
  • Set number of minutes to elapse until sample start
  • Set number of minutes of operation until shutdown
  • Extend short-term samples over an extended period to meet TWA requirements with fewer samples
  • Delayed start
  • Timed shutdown
  • Intermittent sampling
  •  Extended intermittent sampling up to 7 days — ideal for fenceline monitoring!

Run Time NiCad Battery: 8 hrs minimum at 4000 ml/min and 20 inches water back pressure; dependent on media used.
NiMH Battery: 12 hrs minimum at 4000 ml/min and 20 inches water back pressure; dependent on media used.
Battery Eliminator: Pump will provide extended runs.
Timer Display Range 1 to 9999 minutes (6.8 days). Pump will shut off at 9999 minutes. To reset, restart the pump.
Flow Indicator Built-in rotameter with 250-ml division; scale marked at 1, 2, 3, 4, and 5 L/min
Charging Time(varies with battery capacity and level of discharge) 6 to 8.5 hrs with PowerFlex charger
Power Supply 6.0-V plug-in NiMH battery pack, rechargeable, 3.5-Ah capacity or
6.0-V plug-in NiCad battery pack, rechargeable, 2.0-Ah capacity
A battery eliminator is available (see Ordering Information); use voids the UL Listing for intrinsic safety.
Intrinsic Safety UL Listed for Class I, Division 1 and 2, Groups A, B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III, Temperature Code T3C
ATEX-approved model is available. Contact SKC.
Operating Temperature 32 to 113 F (0 to 45 C)
Storage Temperature -4 to 113 F (-20 to 45 C)
Charging Temperature 50 to 113 F (10 to 45 C)
Operating Humidity 0 to 95% non-condensing
Flow Fault If the pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters flow fault. During flow fault, the pump stops, displays FLOW FAULT, pauses timing functions, and displays elapsed time or pump time. Auto-restart is attempted up to 5 times.
Low Battery Fault Pumps stops, displays LO BATT, pauses timing functions, and displays elapsed time or pump time.
Battery Test LCD indicator shows battery condition prior to sampling
Time Display LCD displays up to 9999 minutes (6.8 days) at which point the display rolls over to 0. Displays include sampler run time in minutes for sampling period elapsed time, pump run time, or total elapsed time including delayed start
Delay On Allows user to select minutes to delay start of test up to 9999 minutes (6.8 days)
Timed Shutdown Allows user to select minutes of operation before automatic shutdown. Timed shutdown maximum is 9999 minutes (6.8 days)
Timing Accuracy ± 0.05% (± 45 sec/day)
Intermittent Sampling Programmable to allow user to extend short-term samples over an extended period of time to meet time-weighted average (TWA) requirements with a reduced number of samples. Elapsed time maximum is 9999 minutes (6.8 days), at which time the sample pump shuts down.
Sampling Pause (Hold) Allows user to temporarily halt sampling without loss of timing data. Restart does not require resetting time.
Multiple-tube Sampling Built-in constant pressure regulator allows user to take up to four simultaneous samples with rates up to 500 ml/min each (total combined flow 1350 ml/min maximum) using the optional adjustable low flow holder accessory
