Low Level Oxygen Measurement In-Line

The InPro 6900iG/12/120 is designed for processes that require high accuracy at low oxygen concentrations, such as N2 blanketing and inertization.

Very Stable Oxygen Measurement

The large surface area of the cathode electrode and the guard ring for scavenging oxygen molecules ensure stable measurements.

Real-Time Sensor Performance Monitoring

The InPro 6900iG/12/120 uses ISM technology to provide advanced diagnostics, including days until the membrane kit should be replaced.

Accurate at Low Oxygen Concentrations

The InPro 6900iG/12/120 offers reliable measurement between 0.1% and 60% oxygen at an accuracy of 50 ppm. This makes it suitable for applications that need measurement at a low ppm level and require high operational availability.

Suited to Your Process Needs

To meet the requirements of your specific application, the InPro 6900iG/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 6900iG/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.

Plan Maintenance with ISM Diagnostics

ISM technology in the InPro 6900iG/12/120 monitors sensor stress to provide a prediction for upcoming calibration needs. It also tracks electrolyte levels to identify evaporation and leakage, and informs you when refilling is required.
