Flow Range: 1000 to 5000 ml/min (5 to 500 ml/min requires optional
low fl ow adapter kit)
Compensation Range: 5000 ml/min at 10 inches water back pressure
4000 ml/min at 20 inches water back pressure
2000 ml/min at 50 inches water back pressure
Typical Back Pressure of Sampling Media (inches water)
Compare the information in this table to pump compensation range to determine appropriate applications.
Flow Compensation
System:
Patented* isothermal closed loop fl ow sensor
Accuracies: Timing: 1 min/mo at 25 C
Flow Rate: ± 5% of set-point after calibration to
desired fl ow
Battery Charge
Level Indicator:
Icon displays on LCD at full, mid, low charge, imminent
low battery fault, and low battery fault.
Temperature Range: Operating: 32 to 113 F (0 to 45 C)
Charging: 32 to 113 F (0 to 45 C)
Storage: -4 to 95 F (-20 to 35 C)
Operating Humidity: 0 to 95% non-condensing
Typical Run Time † :
XR5000 Model 2 L/min 5 L/min
High-power Li-Ion 40 hrs 22 hrs
Standard Li-Ion 20 hrs 11 hrs
† Results of run time tests using 37-mm, 0.8-μm MCE filters with new pumps and
batteries. Pump and battery performance may vary.
For extended run times, the pump may be operated while
attached to the charger.
Timed Run, Run Delay,
and Continuous Run
1 to 9999 minutes (6.8 days). If run time exceeds
Display Range: 6.8 days, timer display rolls over.
Flow Fault: If pump is unable to compensate for > 15 seconds due to
excessive back pressure, the pump stops, displays fl ow
fault icon, and holds run time display. Auto-restart is
attempted every 15 seconds up to 5 times.
Low Battery Fault: 15 seconds to sleep
