一般描述
| 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 |
| Dimensions | 2.25 in. D x 4.25 in. H x 4.0 in. W (5.7 cm D x 10.8 cm H x 10.2 cm) with battery pack |
| Power Supply | 4.8 V battery pack of four NiMH cells (units mfg before October 2011 contain NiCd cells) |
| Battery Pack Capacity | 2.8 amp hours (NiMH version); 2.4 amp hours (NiCD version) |
| Battery Pack Recharge Time | 14-16 hours overnight with Omega Battery Charger |
| Typical Battery Pack Life | 300 or more charging cycles |
特点和优势
- Patented electronic laminar flow control
