Zefon 805560 Escort Elf Sampling Pumps

Zefon 805560 PUMP, ESCORT ELF WITH SAMPLING LINE, 120V CHARGER

Escort ELF air sampling pumps feature a state of the art electronic laminar flow sensor to provide a constant flow control with ± 2.5% regulation of flow rate (from 1-3 lpm) with automatic compensation for changes in battery voltage, temperature, altitude, and sample load. An internal secondary standard calibrates the pump continuously and needs to checked against a primary standard only once per month (or every 200 hours for coal mine dust sampling).

Features:

  • 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.
  • 2 Year Warranty.

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.
  • ATEX Approved models available. Contact Zefon or your Zefon distributor for details.

Specifications

Operating Flow Control
Volumetric flow rate held within ± 2.5% of set-point over the 1-to-3 lpm operating range (± 5% to 0.5 lpm), with automatic compensation for battery voltage, altitude, temperature and sample load changes.
Flow Rate
Flow rate adjustable between 0.5 and 3 lpm; lower flow rates attainable (to 1 mlpm) with optional Gemini Twin-Port Sampling accessory.
Flow Indication
Liquid Crystal Display provides 0.01 lpm resolution.
Operating Range
30 inches of water load up to 2 lpm and 10 inches up to 3 lpm.
Flow Blockage Detection
Flow-Fault LED comes on immediately 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 fl ow blockage or low battery shutdown and when pump is off or in hold mode.
