Zefon Escort ELF

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 IP65 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.
