High-accuracy oxygen analyzer 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-, 19" rack-, panel- and wall-mounted for flexible installation.

• Easy to use HMI
• High accuracy ( ±0.02 ppm in lowest range)
• Four measurement ranges with 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
