Sample Draw Transmitter

Sample DrawThe Sample-Draw Transmitter is a single gas detector, which allows users to extract a gas sample from deep shafts, tall ceilings, wells, pits and many other locations where it is either, difficult or impossible to place a diffusion sensor. An internal motorized pump provides the power to transport gas samples to the sensor. This instrument can be configured for the detection of hydrocarbon, oxygen or other toxic gases in a wide variety of applications.

 

KEY FEATURES

  • Reliable method for sampling difficult to access areas
  • Accepts sample lines up to 100 ft.
  • Flowmeter with low-flow indicator
  • Robust pump operates on 12 or 24 VDC, thereby reducing installation costs
  • NEMA 4X, weather & corrosion resistant housing

 

APPLICATIONS

  • Wastewater Treatment

Barscreen rooms, effluent, wetwells, sewage lift stations, chlorine treatment/storage areas, digesters, permit-required confined spaces and grit settling area monitoring
