Single-Zone Refrigerant Gas Monitor

Single-Zone Refrigerant Gas Monitor

Precision Refrigerant Monitor for Emissions Reduction
  • Industry-leading 1 ppm Minimum Detectable Level (MDL) for refrigerants
  • Proprietary infrared (NDIR) sensor accurately detects 60+ different refrigerants, including CFCs, HFCs, HCFCs,
    HFOs and natural refrigerants
  • Identify leaks early to mitigate refrigerant loss, protect produce, enhance energy efficiency
  • Helps ensure compliance with refrigeration standards and regulations, such as ASHRAE 15, EN 378, and CARB
  • Industry-leading sampling times / distances with high performance pump (up to 1,200 ft / 365 m)
  • No calibration required, minimal maintenance


Bacharach's Single-Zone 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 such as ASHRAE 15, EN 378,
and CARB RMP; and delivers cost savings through reduced refrigerant recharge and enhanced energy efficiency.
