O2 Sensor InPro6950iG/12/120

Name: O2 Sensor InPro6950iG/12/120
Brand: Mettler Toledo

The InPro 6950iG/12/120 is an amperometric gas-phase oxygen sensor designed for trace oxygen measurement in CO2 recovery in breweries. This sensor uses Intelligent Sensor Management (ISM) diagnostics to reduce maintenance and downtime.

Material No.: 52206443

Accurate Trace Oxygen Measurement

The InPro 6950iG/12/120 provides an accuracy of ±5 ppm in CO2 recovery applications in breweries, where trace level accuracy is critical.

Save Money with CO2 Recovery

Using the InPro 6950iG/12/120 helps measure and capture CO2 from fermentation so you can reduce CO2 purchases for carbonation.

Real-Time Sensor Performance Monitoring

The InPro 6950iG/12/120 uses ISM technology to provide advanced analytics of sensor health, calibration needs, and remaining membrane lifetime.

Accurate at Low Oxygen Concentrations

The InPro 6950iG/12/120 offers reliable measurement between 5 and 50,000 ppm oxygen at an accuracy of ±5 ppm. It gives you the low concentration measurements you need during CO2 recovery and separation to save you costs on CO2 purchases.

Fast Sensor Replacement for More Uptime

The InPro 6950iG/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.

Meets Your Installation Needs

The InPro 6950iG/12/120 offers a 120 mm length suitable for short to medium length installations. The membrane body includes a silicone O-ring and 316L stainless steel wetted parts, making it appropriate for CO2 recovery in the brewery industry.

Plan Maintenance with ISM Diagnostics

ISM technology in the InPro 6950iG/12/120 monitors sensor stress to provide a prediction for upcoming calibration needs. It also tracks the electrolyte level to identify evaporation and leakage, and informs you when refilling is required.
