The 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.
