The Andros® 6552 gas analyzer / non-dispersive infrared (NDIR) sensor is individually calibrated for operation from 0 to 50°C over the range of specified concentrations. Results are stored within each system to provide accurate analysis. It’s designed to meet or exceed the EN 14624 standard for performance of mobile leak detectors and room controllers of halogenated refrigerants.

You can also benefit from greater design flexibility thanks to the 6552’s small size and low power consumption. And it’s operating system simplifies system integration.


  • Measure up to five gases
  • Apply to any or combination of refrigeration systems that employ FreonsTM and carbon dioxide
  • Streamline system integration via a comprehensive operation system
  • Fit into various enclosures thanks to the 6522’s compact design
  • Nearly eliminate zero drift after the warm-up period


  • Compact size
  • User-defined TTL outputs for interfacing to auxiliary devices or alarms
