The Model C12-17 is a stand-alone gas transmitter designed
to detect potentially hazardous concentrations of
combustible gases in ambient air. Gases and hydrocarbon
vapors such as methane, propane, butane, gasoline, toluene,
hydrogen, and many others can be reliably monitored in
process buildings, analyzer enclosures, pump stations, and
gas compressor stations. In fact, anywhere gases or vapors
may build up to explosive levels can be readily monitored
using this transmitter.
