Spectra O2 Analyzer

Item Code: OXY5500


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.


  • 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

  • Channels - 1

  • Analyte and Measurement ranges - O2 (Oxygen): 0 to 100 ppmv (minimum), 0 to 20% volume (maximum)

  • Measured Variables - Concentration, Cell Pressure, Cell Temperature

  • Ambient Temperature Range - -20 to 50°C (-4 to 122°F)

  • Operating Pressure Range - Inlet Pressure: 140 to 275 kPa (20 to 40 psig), Sample Cell: 800 to 1200 mbara

  • Analyzer Wetted Materials - 304 & 316 stainless steel FKM O-Rings
