Flow
Flow Range: 5 to 15 L/min
Flow Control System: Closed loop with patented* internal fl ow sensor
Compensation Range: 15 L/min at 5 inches water back pressure
10 L/min at 12 inches water back pressure
5 L/min at 20 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.
Accuracy: Flow Rate: ± 5% of set-point after calibration to desired fl ow
Timing: 1 min/month at 25 C
Atmospheric Pressure: ± 0.3 in Hg
Flow Fault: If the pump is unable to compensate for > 15 seconds due
to excessive back pressure, a fl ow fault icon displays and
fl ashes, the pump enters Hold mode, and the pump retains
historical data. Auto-restart is attempted every 20 seconds
up to 10 times. Adjustable with DataTrac for Leland Legacy
Software. See pages 18 and 20.
Tubing: Requires 3/8-inch ID tubing
Operation
Display: LCD displays pump serial number, pump software revision
level, flow rate, volume, temperature, atmospheric
pressure, time of day, run time, and pump status, i.e., Hold
and run as well as Setup information.
Volume Display: Continually updated, based on corrected fl ow rate
multiplied by sampling time. When volume exceeds
99,999 liters, the pump will continue to run normally but
an O_FLO Error will appear on the LCD.
Time Display: Time of day in hours and minutes (12 or 24-hour clock)
with AM and PM indicators
Timer Display Range: 1 to 99,999 minutes (69 days). If the run time exceeds
69 days, the timer display rolls over.
Operating Temp. Range: 32 to 113 F (0 to 45 C)
Protect sample pump from weather when
in use outdoors.
Altitude: Do not use pump beyond 7500 ft.
Operating Humidity: 0 to 95% non-condensing
Typical Run Time: † • Sioutas Impactor (approx. 13 in water bp): 24 hrs at
9 L/min
• PEM with 37-mm, 2.0-μm PTFE fi lter 225-1709 ‡ :
24 hrs at 10 L/min
• Low-volume PUF Tube: 24 hrs at 5 L/min
• DPS Sampler (PM2.5 or PM10): 24 hrs at 10 L/min
• 8 L/min Respirable PPI: 24 hrs at 8 L/min
• For extended run times, the pump may be operated
while attached to the approved charger.
