The Polytector III G999M is a modern and versatile multi-gas detector. With its five sensor slots (3x electrochemical for toxic gases, oxygen and hydrogen, 1x catalytic combustion for combustible gases and vapors, 1x infrared for carbon monoxide and combustible gases) it is able to monitor up to eight gas concentrations simultaneously. The G999M is approved for use in mining as well as Ex zone 0.
