O2 Sen InPro6850iG/12/120/1611111

Name: O2 Sen InPro6850iG/12/120/1611111
Brand: Mettler Toledo

The InPro 6850iG/12/120 is an amperometric gas-phase oxygen sensor that is suited to a wide measurement range in a broad choice of applications. This sensor uses Intelligent Sensor Management (ISM) diagnostics to reduce maintenance and downtime.

Material No.: 52206431

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 changes in oxygen levels (90% in under 20 seconds), and the membrane is insensitive to dust and moisture. This provides fast, accurate readings in the process stream.
