The GPR-2800 series of process oxygen analyzers allows measurements of 0-1 up to 0-25% O2 in hazardous area. Combined with our modular sample system, the gas analyzer will suit most installations for demanding oxygen analysis and will meet the needs of process customers around the world. Analytical Industries' proprietary long-life oxygen sensor technology allows a maintenance-free sensor operation of up to 32 months for low cost of ownership. The industry-proven and well recognised electrochemical gas sensor quality ensures the reliability of oxygen content measurements even at high carbon dioxide background.

  • UL or ATEX certified for use in hazardous areas
  • Four measurement ranges 0-1%, 0-5%, 0-10% & 0-25% O2
  • Low maintenance with an average sensor life of up to 32 months (for GPR sensor)
  • Sample in CO2 backgrounds with XLT sensor
  • Easy to use HMI
  • Optional Modbus communications
  • Optional liquid drain option for removing entrained liquids
