The AII GPR-2600 Oxygen Analyzer is designed for monitoring gas in industrial processes where trace oxygen from low parts per million to pure O2 has to be precisely measured. Utilizing AII's high performance galvanic oxygen sensors these advanced instruments are simple to use with a common, across-the-range chassis, HMI and menu structure, so an operator only needs to learn operation of just one instrument for multiple gas analysis applications at various oxygen levels. Available as bench, 19in rack, panel and wall mounted for flexible installation. The GPR-2600 monitors oxygen in applications which involve purging from ambient air to low percentage levels of oxygen with a variety of gases.

Applications for the GPR-2600 include:

• Purity of product in industrial gas manufacture
• Trace oxygen in hydrogen generation by electrolysis
• Monitoring oxygen generators
• Measuring oxygen in metallurgical processesheat treatment and annealing
• Gas measurement in poultry stunners
• Analysis of gas in double glazing manufacture

• Measuring range:
• 0-1%, 0-5%, 0-10%, 0-25%
• High accuracy (±0.02ppm in lowest range)
• Manual or auto-ranging
• 24 month sensor life with normal usage
• Sample in CO2 backgrounds with XLT sensor
• Bench, rack or wall mounting options
• Two Alarms
• Integrated bypass valve (for GPR-1600)
• Easy access and sensor replacement
• Easy to use HMI
