Analytical Industries Oxygen Analyzers for Industrial Gases

 High-accuracy oxygen analyzers 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.

As standard the GPR-1600 has an integral bypass sample system. The analyzer can be temporarily exposed to ambient air to perform a span calibration (20.9% O2).
Options: External bypass system, Heated sample system
Measurement ranges: 0-10 ppm, up to 0-1% O2 (0- 25% for calibration only).

GPR-2600

The GPR-2600 is an ideal instrument to monitor oxygen in applications which involve purging from ambient air to low percentage levels of oxygen with a variety of gases.
Options: Heated sample system
Measurement ranges: 0-1% up to 0-25% O2fGPR-3100

The GPR-3100 is fitted with a temperature controlled sample handing system to provide an isothermal environment for the sample for increased accuracy.
Measurement ranges: 0-100% up to 90-100% O2
