The Model 610A is a system for continuously monitoring combustible gas (hydrocarbon) concentrations in four locations. The system consists of four remote catalytic sensing assemblies and a solid-state controller. The controller features four independent channels, each having its own circuitry. The 610A features a digital display of gas concentrations in % LEL (0-99% lower explosive limit) for each channel.
