Specifications
Operating Flow Control	Volumetric flow rate held within ± 2.5% of set-point over the 1 to 3 L/min operating range (± 5% to 0.5 LPM), with automatic compenstation for battery voltage, altitude, temperature, and sample load changes.
Flow Rate	Flow rate adjustable between 0.5 and 3.0 L/min; lower flow rates attainable (to 1 mL/min) with the optional Gemini Twin-Port Sampling accessory
Flow Indication	Liquid crystal display (LCD) provides 0.01 L/min resolution
Operating Range	30 inches of water load upt to 2 L/min and 10 inches up to 3 L/min
Flow Blockage Detection	Flow-fault LED comes on immedieatly when block is detected. Pump shuts down within 90 seconds if block is not cleared.
Elapsed Time Readout	To 999 minutes in increments of 1 minute. Holds the last reading after either flow blockage or low battery shutdown and when pump is OFF or in HOLD mode.
Operating Time	Varies with flow rate and sample device loading.
Operating Temperature Limits	32-113 °F (0-45 °C)
Physical Weight	23 oz. (652 g) with battery pack
