In-Line Gas Phase O₂ Measurement
The InPro 6850iG/12/120 is designed to measure gas-phase oxygen in-line, in harsh environments and hazardous area applications.
Signal Stability & Reduced Maintenance
The 3-electrode system of the InPro 6850iG/12/120 includes a platinum anode that increases signal stability and extends maintenance intervals.
Real-Time Sensor Performance Monitoring
The InPro 6850iG/12/120 uses ISM technology to provide advanced diagnostics, including days until the membrane kit should be replaced.

Reliable in Harsh Processes The InPro 6850iG/12/120 offers accurate measurement between 0.1% and 100% oxygen, making it suitable for challenging applications such as off-gas monitoring or inertization in aggressive processes. |
Suited to Your Process Needs To meet the requirements of your specific application, the InPro 6850iG/12/120 is 120 mm long for small to medium length installations. It uses a standard silicone O-ring with 316L stainless steel wetted parts. |
Fast Sensor Replacement for More Uptime The InPro 6850iG/12/120 offers an easy-to-change membrane body and ISM Plug and Measure technology. Plug and Measure allows a sensor to be polarized and calibrated away from the process under lab conditions, and then inserted directly into the process. |
Accurate, Quick Measurement The InPro 6850iG/12/120 responds very quickly to oxygen levels changes (90% in less than 20 seconds), and the membrane is insensitive to dust and moisture. This provides fast, accurate readings in the process stream. |
