Overview of Primary Product

Low Maintenance Continuous Monitoring
The Bacharach Single-Zone family of xed point gas monitors is available for the detection of refrigerants, halogen
gases (HGM-SZ) and ammonia (AGM-SZ). The Single-Zone series is designed around Bacharach’s proprietary
infrared sensing technology to offer reliable, superior sensing performance.
Bacharach’s infrared (NDIR) sensors offer users one of the most feature loaded, lowest-cost-of-ownership
monitors available. The Single-Zone monitors feature automatic calibration, eliminating the need for costly
calibrations. Periodic lter replacements are practically the only maintenance required.
An easy-to-install, out-of-the-box solution, Bacharach’s Single-Zone monitors offer an onboard power supply, LCD
display for real-time readings and LED indicators with dedicated relays that activate audible or visual alarms. A
4-20 mA output enables a compatible connection to standard building automation systems.
