Description

AII GPR 1600/2600/3100 Oxygen Analyzers for Industrial Gas

Percent and PPM O2 Monitoring in Bulk Gases

AII GPR 1600/2600/3100 Oxygen Analyzers range of oxygen analyzers are designed to monitor gas produced or used in industrial processes where trace oxygen from low parts per million to pure O2 must be precisely measured. Utilizing AII’s high performance galvanic oxygen sensors these advanced instruments are simple to use with a common HMI and menu structure across-the-range chassis. Operators only need to learn just one instrument for multiple gas analysis applications at various oxygen levels. Available as bench-, 19″ rack-, panel- and wall-mounted for flexible installation.

 

AII GPR 1600/2600/3100 Oxygen Analyzers Features:

  • High accuracy ( ±0.02 ppm in lowest range)
  • 24 months sensor life with normal usage
  • Sample in CO2 backgrounds with XLT sensor
  • Four measurement ranges with manual or auto-ranging
  • Two Alarms and range indication output
  • Bench, rack or wall mounting options
  • Integrated bypass valve (for GPR-1600)
  • Easy access and sensor replacement
  • Simple to use HMI
