General description

Specifications
Operating Flow ControlVolumetric 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 RateFlow 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 IndicationLiquid crystal display (LCD) provides 0.01 L/min resolution
Operating Range30 inches of water load upt to 2 L/min and 10 inches up to 3 L/min
Flow Blockage DetectionFlow-fault LED comes on immedieatly when block is detected. Pump shuts down within 90 seconds if block is not cleared.
Elapsed Time ReadoutTo 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 TimeVaries with flow rate and sample device loading.
Operating Temperature Limits32-113 °F (0-45 °C)
Physical Weight23 oz. (652 g) with battery pack
Dimensions2.25 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 Supply4.8 V battery pack of four NiMH cells (units mfg before October 2011 contain NiCd cells)
Battery Pack Capacity2.8 amp hours (NiMH version); 2.4 amp hours (NiCD version)
Battery Pack Recharge Time14-16 hours overnight with Omega Battery Charger
Typical Battery Pack Life300 or more charging cycles

Features and Benefits

  • Patented electronic laminar flow control
  • Internal secondary standard calibrates the pump continuously, maintaining OSHA compliance
  • Check against a primary standard only once a month or every 200 hours for coal mine dust sampling
  • Inlet filter traps moisture and particular matter
  • Stainless steel-filled plastic case provides EMI/RFI protection
  • Rated IP66 for resistance to water and dust ingress
  • Exceptionally quiet operation
  • Flow-Fault Indicator shows any sample inlet blockage
  • Run/Hold feature allows "time out" during sampling process
  • Elapsed time readout and low-battery warning
  • Low flow and dual tube sampling available with Gemini Twin-Port Sampler (28118-U)

Suitability

Approvals
  • NIOSH certified for coal mine dust sampling (TC-74-030)
  • MSHA certified as intrinsically safe for underground use (Approval # 2G-3924-1).
  • UL approved as intrinsically safe for use in hazardous locations, Class I, Groups A, B, C, D; Class II, Groups E, F and G; Class III, Division I locations.
