Description

The OXY5500 oxygen analyzer is a compact, stand-alone, single channel analyzer that uses quenched fluorescence (QF) technology to reliably measure oxygen in natural gas and gas processing applications. A sensor probe is inserted into the process stream and is connected to the controller by an optical fiber. Featuring an LCD display and built-in data logger, the OXY5500 also has full sample conditioning systems available as well as software for a PC interface.

Field of application
  • Natural gas quality measurements in production, storage, transportation, and distribution
  • Monitoring in natural gas, upstream of production and gathering sites
  • Measurable range from ppm levels to 0-20% O2
  • Trace measurements as low as 0-10 ppmv oxygen in hydrogen for electrolyzer applications
  • Ideal for CCUS applications since optical oxygen measurement is unaffected by CO2 or H2S in the process
Benefits
  • Easy to navigate display and menu
  • Small optical sensor with no membrane or consumable chemicals
  • Optical measurement with fast, continuous response
  • Excellent long-term stability
  • Not affected by H2S
  • No moving parts, simple operation
  • Data logging for 30 days
