  • Support
The Universal PCXR8, 5 to 5000 ml/min, programmable personal or area sample pump provides up to 12-hour run times or extended intermittent sampling for particulates and gases/vapours. 
 
The pump is ideal for use with sorbent tubes, filter cassettes, size-selective samplers, sample bags, and impingers. The PCXR8 Universal Sample Pump is UL Listed for intrinsic safety. 
 
Built-in high-accuracy timer
  • Sample duration readout
Convenient hold feature
Automatic fault shutdown/time retention
  • Ensures sample integrity upon low battery or excess back pressure

Delayed start

  • Set number of minutes to elapse until sample start
Timed shutdown
  • Set number of minutes of operation until shutdown
Intermittent sampling
  • Extend short-term samples over an extended period to meet TWA requirements with fewer samples
  • Extended intermittent sampling up to 7 days — ideal for fenceline monitoring!
One-year warranty
Ultra-quiet operation
Pulsation-free flow
Impact-resistant case
Flow Range
1000 to 5000 ml/min (UL Listed model)
(5 to 500 ml/min requires the 224-26 Series adjustable low flow holder)
Requires 1/4-inch ID tubing
Weight 34 oz (964 gm)
Dimensions 5.1 x 4.7 x 1.9 in (13 x 11.9 x 4.8 cm)
Compensation Range
1000 to 2500 ml/min at 40 inches water back pressure
3000 ml/min at 35 inches water back pressure 
4000 ml/min at 20 inches water back pressure
5000 ml/min at 10 inches water back pressure
Flow Control Holds constant flow to ± 5% of set-point
Run Time
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 will provide extended runs.
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
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 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 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 indicator shows battery condition prior to sampling
Delay On 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
Timed Shutdown
Allows user to select minutes to delay start of test up to 9999 minutes (6.8 days)
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
RFI/EMI Shielding
Complies with requirements of EN 55022, FCC Part 15 Class B, EN 50082-1
Frequency range of the radiated susceptibility test was 27 to 1000 MHz
CE marked
