The AII GPR-3100 Oxygen Analyzer is fitted with a temperature controlled sample handing system to provide an isothermal environment for the sample for increased accuracy. The GPR-3100 is 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.

Applications: 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.
