Single-Zone Refrigerant Monitor
Precision Monitoring for Low-level Refrigerant Leak Detection for Small to Medium Size Facilities
Bacharach’s Single-Zone Refrigerant Monitors 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
- Gas library contains 50+ refrigerants, with Halogen, CO2 and NH3 versions available
- Backlit display shows real-time concentration readings and makes configuration and self-diagnostics intuitive
- High performance sampling pump for fast response times, including extending sample lines
Product Information
Bacharach’s Single-Zone Refrigerant Monitor delivers the best refrigerant leak detection available, with industry-leading MDL of 1ppm for halogenated gases, the fastest sampling frequency and the widest range of refrigerants accurately detected. The Single-Zone is the ideal tool for early detection of leaks from specific target areas such as chiller rooms and mechanical rooms. The low MDL enables detection of leaks that other instruments can’t find; enhances effective refrigerant management and compliance with refrigeration standards and regulations that require refrigerant emissions reduction such as EPA Section 608, CARB, and European F-Gas compliance. The Single-Zone Refrigerant Monitor delivers cost savings through reduced refrigerant recharge and enhanced energy efficiency.
