Flow Range	1000 to 3250 ml/min (5 to 500 ml/min requires optional low flow adapter kit)
Compensation Range	3000 ml/min at 15 inches water back pressure 2000 ml/min at 30 inches water back pressure 1000 ml/min at 30 inches water back pressure
Flow Fault	If the pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters flow fault mode. During flow fault, the pump enters Hold, the fault icon appears on the display during the length of the fault, and the accumulated run time display is frozen and retained. After 5 minutes in flow fault, auto-restart is attempted every 5 minutes up to 10 times.
Run Time	With NiMH battery pack, run time is 12+ hours for 2000 ml/min and up to 30 inches water back pressure; dependent on sample media used. With Battery eliminator, run time is extended.
Charging Time (varies with battery capacity and level of discharge)	6 to 8.5 hrs with PowerFlex charger
Flow accuracy	± 5% of set-point after calibration to desired flow
Flow Control	An internal isothermal flow sensor measures flow directly and continuously. Sensor readings are used in a flow monitoring algorithm to maintain calibrated volumetric flow. In addition, built-in atmospheric temperature and pressure sensors provide readings to correct volumetric flow for these parameters when they vary from point of calibration.
Atmospheric Pressure Accuracy	± 0.3 in Hg
Timing Accuracy	1 min/mo at 25 C
Operating Temperature Range	32 to 113 F (0 to 45 C)
Charging Temperature Range	50 to 113 F (10 to 45 C)
Storage Temperature Range	-4 to 113 F (-20 to 45 C)
Altitude	The pump can apply correction to volumetric flow during sampling for weather-related or altitude variations from the atmospheric pressure established at calibration up to at least 7500 feet above and 5000 feet below sea level.
Battery Pack	Removable chargeable 4-cell NiMH battery, 4.8 V x 3.5-Ah capacity
Tubing	Requires 1/4-inch ID tubing
Size	5.6 x 3 x 2.3 in (14.2 x 7.6 x 5.8 cm)
Weight	22 oz (624 gm)
Intrinsic Safety	UL and cUL Listed ATEx and ANZEx models available
Case	Impact resistant RFI/EMI shielded CE marked
