HZ678-MGS-450 R-404A Gas Detector

• 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
