Bacharach, a world leader in the design, manufacture and service of advanced test and measurement instrumentation, introduces its latest innovation in fixed-system monitors, the MGS-550 Gas Detector. The MGS-550 can utilize any combination of sensor technologies, including electrochemical, semiconductor (MOS), catalytic bead or infrared in a single platform for unparalleled detection capability. Its single or dual sensor capability (with remote placement option) can detect refrigerants (including NH3 and CO2), combustibles, toxic gases and VOCs in industrial, commercial and institutional environments. The MGS-550 features a magnetic wand for non-intrusive configuration and calibration without the need to open the enclosure. It also offers analog and Modbus interfaces, three user-assignable relays and a simple intuitive menu for easy installation and training. Able to function as a standalone unit or as part of any BMS control system, its two enclosure options (IP66 ABS or explosion-proof aluminum) provide durable performance in any location.  Learn more at
