The Bacharach Multi-Zone Gas Monitor is a high-performance gas leak detection system designed for professional use. Known for its exceptional accuracy and industry-leading sensitivity down to 1 ppm, this unit supports up to 48 sampling points and detects a wide range of gases, including halogenated refrigerants, ammonia, and carbon dioxide. Its fast sampling frequency and NDIR sensor technology ensure early leak detection, helping reduce refrigerant loss, improve energy efficiency, and prevent system failures. Fully compliant with key refrigeration safety standards such as ASHRAE 15, EN 378, and CSA-B52, and emissions regulations like F-Gas and CARB RMP, the Multi-Zone is ideal for commercial and industrial applications. It integrates easily into building management systems via Modbus RTU, BACnet, or LonWorks, enabling remote monitoring and control. The backlit graphic LCD interface with status LEDs provides at-a-glance system overview, and the device includes integrated visual and audible alarms (80 dB). Perfect for installation in refrigeration systems, data centers, supermarkets, and industrial environments.
