Oxygen Sensor InPro 6900iG/12/120/Ka
Low Range, Gas-Phase Oxygen Sensor
The InPro 6900iG/12/120/Ka is an amperometric gas-phase oxygen sensor that is designed for low oxygen range applications with an accuracy of 50 ppm. This sensor uses Intelligent Sensor Management (ISM) diagnostics to reduce maintenance and downtime.
Low Level Oxygen Measurement In-Line
The InPro 6900iG/12/120/Ka 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/Ka uses ISM technology to provide advanced diagnostics, including days until the membrane kit should be replaced.

Features and Benefits
|Accurate at Low Oxygen Concentrations|
The InPro 6900iG/12/120/Ka 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/Ka is 120 mm long for short to medium length installations. It uses a Kalrez® O-ring with 316L stainless steel wetted parts for wide application coverage.
|Fast Sensor Replacement for More Uptime|
The InPro 6900iG/12/120/Ka 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/Ka monitors sensor stress to provide a prediction for upcoming calibration needs. It also tracks electrolyte level to identify evaporation and leakage, and informs you when refilling is required.
