O2 Sensor InPro6900iG/12/120
Low Range, Gas-Phase Oxygen Sensor.The InPro 6900iG/12/120 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 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.

Accessories
Sensor Calibration & Maintenance Tools
The DS AK9-RJ12 is a USB cable adaptor for connecting ISM 1-wire sensors to iSense software. This allows pH, DO and CO2 sensors to be evaluated, maintained and calibrated in the workshop or laboratory.
Diagnostics Away From the Transmitter
The iLink module allows you to access all of the diagnostics of your ISM sensors away from the process with iSense desktop software.
Application Profiling Drives Performance
Store application data on iSense and load directly into an ISM sensor. This allows sensors to learn from preceding sensors in the same process.
Easy Access to Paper Free Documentation
The iLink cable allows sensor calibration and adjustment protocols to be generated automatically in iSense and stored in a fully digital database.
