MC600 Multi-Channel Controller

The MC600 is a microprocessor-based multi-channel controller that provides six channels of continuous gas detection. It can be configured as either a local gas detection system, or it can be networked to provide a large plant-wide distributed safety system. It is compatible with our hydrocarbon sensors, H2S sensors, as well as our S4000CH, S4100C, S4000TH, S4100T, IR400, IR5500, IR700, TS4000H, Observer, and Surveyor gas detectors.
