Trace Amperometric Oxygen Gas Sensors

In-line amperometric sensors for trace oxygen gas measure directly in the process without the need for expensive gas sampling equipment. The maintenance requirement for the sensors is minimal and any work required can be performed without process interruption. Accurate measurement is assured due to the moisture and dust impermeable membrane covering. Hazardous area approval for the InPro6900i G makes it appropriate for challenging applications such as N2 blanketing, inertization and off-gas monitoring. The InPro6950i G, with its FDA approval, is particularly suited for brewery and food & beverage applications.

Model	Operating Range	Accuracy	Measuring Pressure Resistance
InPro6900i G	50 ppm to 60 Vol-% O2	≤ ± [1% +50 ppm]	0.2 to 9 bar (2.9 to 130 psi absolute)
InPro6950i G	5 ppm to 50,000 ppm	≤ ± [1% +5 ppm]	0.2 to 9 bar (2.9 to 130 psi absolute)
