The Bacharach MGS-450 Gas Detector is engineered for the detection of refrigerants, toxic gases, and combustible gases, meeting global safety standards such as ASHRAE 15, EN 378, and CSA-B52. Supporting various sensor technologies — electrochemical, semiconductor (MOS), catalytic bead, and infrared — it delivers reliable and accurate monitoring. Easily integrated into building management systems via analog outputs or Modbus RTU, the MGS-450 features two alarm relays, one fault relay, and a built-in audible/visual alarm. Its robust IP41 or IP66-rated enclosure ensures durability in demanding environments. Key specifications include an operating temperature range from -40 to +50°C, accuracy up to ±5% of full scale (sensor dependent), and compatibility with a wide selection of gases including R-32, R-404A, ammonia (R-717), and CO₂ (R-744).
