The Bacharach MGS-450 Gas Detector delivers high-performance detection of refrigerants, toxic gases, and combustible gases. Its advanced design supports a variety of sensing technologies — electrochemical, semiconductor (MOS), catalytic bead, and infrared — providing flexibility for different applications. Compliant with ASHRAE 15, EN 378, and CSA-B52, the MGS-450 can operate as part of a building’s control network via Modbus RTU or analog outputs. Integrated audio/visual alarms, dual alarm relays, and a fault relay help maintain safety without additional hardware. Notable features include rugged IP41/IP66 construction, operation from -40 to +50°C, and detection of numerous gases including R-134a, R-32, R-404A, ammonia (R-717), and CO₂ (R-744).
