NOTE: The IP41 enclosure provides dust protection only and is best for dry conditions where only dust protection is needed. NOT RECOMMENDED for refrigerated spaces. For moisture and temperature protection, use the IP66 enclosure equivalent part 6302-2167.
Compatible with Calibration Gas Cylinder part 0051-4193.
Transformer 640-0039-HL is recommended for this leak detector.
MGS-450 Gas Detector
Safety Gas Detection for Refrigerants, Toxic and Combustible Gases
MSA 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 MSA 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
