Multi-Zone Gas Monitor

Industry Leading Precision Monitoring for Low-level Gas Leak Detection

MSA Bacharach’s Multi-Zone Gas Monitor provides precise measurements enabling early leak detection for compliance with refrigeration safety codes (ASHRAE 15, EN 378, CSA-B52) and emissions reduction standards (F-Gas, CARB).

• Proprietary infrared (NDIR) sensor accurately detects the presence of a target gas down to an industry-leading 1 ppm Minimum Detection Level (MDL)
• Sensor is not prone to false alarms caused by cross-interference from other gases or sudden changes in temperature or humidity
• Backlit display shows real-time concentration readings and makes configuration and self-diagnostics intuitive
• Capable of monitoring up-to 16 zones (expandable up to 48 sample points) and detecting multiple gases with a single monitor
• Two optional analog outputs (4-20mA) and Modbus communications (slave) for integration with third-party BMS / BAS control systems
• Three user-configurable relays (leak, spill and evacuate) may be used to activate external beacons / sounders, ventilation or other countermeasures

MSA Bacharach’s Multi-Zone Gas Monitor delivers the best refrigerant leak detection available, the fastest sampling frequency and the widest range of refrigerants accurately detected. The large graphic LCD display and LED status indicators provide a system-wide overview at a glance.

The Multi-Zone enhances effective refrigerant management and ensures compliance with refrigeration safety standards (ASHRAE 15, EN 378, CSA-B52) and emissions regulations (F-Gas, CARB RMP). It detects leaks early to enable cost savings by reducing refrigerant recharge, enhancing energy efficiency and reducing risk of refrigeration failure and produce loss. A variety of communication interfaces are available including Modbus, BACnet and LonWorks, allowing easy integration into BMS / BAS systems and remote monitoring solutions.
