Mettler Toledo Dissolved Oxygen Sensor InPro InPro6860i/12/120/nA

Mettler Toledo 30014100 InPro 6860i Digital Optical Dissolved Oxygen Sensor (12/120/nA)

The Mettler Toledo 30014100 (InPro 6860i) is a state-of-the-art optical dissolved oxygen (DO) sensor designed for the rigorous demands of pharmaceutical and biotechnology production. Utilizing advanced fluorescence quenching technology, this sensor provides high-accuracy oxygen measurements with exceptional signal stability and short response times. As an "i" series sensor, it features Intelligent Sensor Management (ISM®) for predictive diagnostics and "Plug and Measure" simplicity. Uniquely, this model provides both a digital signal and a simulated nA analog output, allowing it to interface seamlessly with modern digital control systems and legacy analog transmitters or benchtop bioreactors.

Technical Performance and Design

• Optical Measurement Technology: Uses fluorescence quenching for oxygen detection, eliminating the need for electrolyte handling and sensor polarization, which significantly reduces maintenance time and human error.

• Universal Connectivity (nA/Digital): Features a simulated electrochemical (nA) signal for compatibility with older analog equipment, alongside RS485 digital integration (Modbus RTU and ISM) for modern data architectures.

• Intelligent Sensor Management (ISM®): Provides real-time predictive diagnostics, including the Dynamic Lifetime Indicator (DLI) and Adaptive Calibration Timer (ACT), which alert users exactly when the OptoCap™ needs replacement.

• Hygienic & Durable Construction: The 316L stainless steel body features an N5/Ra16 polished finish. The OptoCap™ sensing element is PTFE-coated to prevent biofouling and is designed to withstand repeated SIP, CIP, and autoclaving cycles (up to 140°C).

Key Benefits & Applications

• Bioprocess Control: Optimized for fermentation and cell culture where consistent oxygen levels are critical for cell growth and product yield.

• Reduced Maintenance: The electrolyte-free design and easy-to-replace OptoCap™ reduce the Total Cost of Ownership (TCO) compared to traditional polarographic sensors.

• Enhanced Uptime: Pre-calibration capability using iSense software allows sensors to be calibrated in the lab and hot-swapped into the process without further field calibration.

• Regulatory Compliance: Meets all major industry standards, including FDA and USP Class VI approvals for wetted materials and hygienic design.

Compatibility Note

The InPro 6860i is compatible with Mettler Toledo M400 and M800 transmitters. For analog integration with benchtop bioreactors (e.g., Applikon or Sartorius), the simulated nA output allows for direct connection using standard VP cables without requiring a separate transmitter.
