MGS-450 Gas Detector

MGS-450 Gas Detector

Used for detection of refrigerants, toxic and combustible gases

Bacharach’s MGS-450 Gas Detector makes compliance with refrigeration safety codes (ASHRAE 15, EN 378, CSA-B52) simple and effective, saving time and money on equipment and installation.

  • Optional IP41 or IP66-rated enclosures protect from dust and water ingress
  • Plug-and-play pre-calibrated sensor modules allow for quick, simple sensor replacement
  • Temperature-compensated measurements mitigate false alarms and optimize accuracy in refrigeration applications (suitable for use in cold rooms and freezers down to -40°C)
  • Configurable analog output (4-20mA, 0-5V, 0-10V, 1-5V or 2-10V) and Modbus communications for integration with Bacharach’s MGS-408 controller or third-party BMS / BAS control systems
  • Three user-configurable relays (fault, low and high alarm) may be used to activate external beacons / sounders, ventilation or other countermeasures
  • Integrated audible / visual alarms for refrigeration safety compliance – no additional hardware required
  • MGS-400 mobile app (available for Android and iOS) allows users to interface via Bluetooth® with gas detector for easy commissioning and maintenance without specialty tools or training
