The Universal PCXR4, 5 to 5000 ml/min, personal or area sample pump with timer and flow fault provides up to 12-hour run times for sampling particulates and gases/vapours. 
 
The pump is ideal for use with sorbent tubes, filter cassettes, size-selective samplers, sample bags, and impingers. The PCXR4 is UL Listed for intrinsic safety. 
Automatic fault shutdown and time retention
  • Pump shuts down and retains sampling time when battery is low or there is excessive back pressure to ensure sample integrity
High-accuracy timer
  • Built-in timer provides instant readout of sampling duration.
Convenient hold feature
  • Allows for breaks
One-year warranty
Ultra-quiet operation
Pulsation-free flow
Impact-resistant case
 
Operating Range
1000 to 5000 ml/min (UL Listed model)

5000 ml/min at 10 inches water back pressure
Flow Control Holds constant flow to ± 5% of set-point
Run Time: Battery
NiCad Battery: 8 hrs minimum at 4000 ml/min and 20 inches water back pressure; dependent on media used. See Table 3
NiMH Battery: 12 hrs minimum at 4000 ml/min and 20 inches water back pressure; dependent on media used. See Table 2.
Battery Eliminator: Pump provides extended runs.
Run Time: Mains Adapter 9999 minutes (6.8 days). Pump will shut off as run time cannot exceed timer display. See Timer Display Range below.
Tubing Requires 1/4-inch ID tubing
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
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.
Charging Time (varies with battery capacity and level of discharge) 6 to 8.5 hrs with PowerFlex Charger
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 Air-Met Scientific for more information.
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. Auto-restart is attempted up to 5 times.
Low Battery Fault Pump stops, displays LO BATT, pauses timing functions, and displays elapsed time.
Battery Test LCD indicator verifies 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.
Timing Accuracy ± 0.05% (± 45 sec/day)
Sampling Pause (Hold) Allows user to temporarily halt air 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
