The MH-1200H-S4 uses diffusion sampling, with electrochemical sensors for CO, H2S and O2 and a catalytic combustion sensor for the LEL channel. It provides the four readings through a monochrome LCD and uses sound, light and vibration for alarm indication.\u003c\/p\u003e\u003ch3\u003eFour Gas Channels in One Configuration\u003c\/h3\u003e\u003cp\u003eThe instrument is supplied as one four-channel configuration.
