Flow Range	1000 to 3000 ml/min (5 to 500 ml/min requires Constant Pressure Controller [CPC] and Adjustable Low Flow Holder accessories)
Flow Control	Holds constant flow to ± 5% of set-point after calibration
Compensation Range	1000 ml/min up to 25 inches water back pressure 2000 ml/min up to 25 inches water back pressure 2500 ml/min up to 20 inches water back pressure 3000 ml/min up to 15 inches water back pressure

Run Time	NiCad Battery: 8 hrs minimum at above compensation ranges; dependent on media used. See Table 1. NiMH Battery: 12 hrs minimum at 2000 ml/min and up to 25 inches water back pressure; dependent on media used. See Table 2.
Power Supply	Rechargeable 4.8-V nickel-metal hydride (NiMH) battery pack, 3.3-Ah capacity or Rechargeable 4.8-V nickel cadmium (NiCad) battery pack, 1.8-Ah capacity A battery eliminator is available (see Ordering Information); use voids the UL Listing for intrinsic safety.
Battery Charging Time (varies with battery capacity and level of discharge)	6 to 8.5 hrs using PowerFlex Charger
Temperature	Operating: 32 to 113 F (0 to 45 C) Storage: -4 to 113 F (-20 to 45 C) Charging: 50 to 113 F (10 to 45 C)
Humidity	0 to 95% non-condensing
Flow Fault	If 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, the fault icon appears on the display, and elapsed time remains on the display. Auto-restart is attempted up to 5 times. Elapsed time information will be lost on restart.
Low Battery Fault	LCD displays low battery icon and pump shuts down. LCD remains on.
LCD Time Display	LCD display shows elapsed pump run time in minutes up to 99,999.
LCD Indicator	LCD always remains on. Displayed elapsed run time information resets when pump is started.
Noise Level	62.5 dBA* - pump without case 55 dBA* - pump housed in noise-reducing case (optional accessory Cat. No. 224-96C) * Pump operating at 2 L/min with a 37-mm, 0.8-µm MCE filter cassette measured at 3 ft (1 m) from pump
RFI/EMI Shielding	Complies with requirements of EN 55022 1987 Class B, and EN 50082-1:1992 Frequency range of radiated susceptibility test was 27 to 1000 MHz. CE marked
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 models available; contact SKC
Dimensions	5 x 3 x 1.75 in (12.7 x 7.6 x 4.4 cm)
Weight	20 oz (567 gm)
Multiple-tube Sampling	Adjustable low flow holder accessory allows user to take up to four simultaneous samples at flows from 5 to 500 ml/min. CPC required
Tubing	Requires 1/4-in ID tubing
