580A双通道气体报警器

The Model 580A is a compact, highly-versatile system for continuously monitoring combustible gas (hydrocarbon) concentrations in two locations. The system consists of two remote catalytic sensing assemblies and a solid-state controller. The controller automatically displays the higher reading channel on a digital display, scaled from 0-100% LEL (lower explosive limit). Manual override switching permits readout of the low channel at any time.
