High-Reliability pH/ORP Sensor with Easily Replaceable Glass Electrode and Liquid Junction
This process pH/ORP sensor features a reinforced PPS resin body that provides excellent corrosion resistance, heat resistance, and mechanical strength.
Developed based on many years of proven performance and field experience, it delivers stable and reliable measurement across a wide variety of applications, including quality control in manufacturing processes, medium-sized wastewater treatment plants, and various pH/ORP control systems.
The glass electrode and liquid junction can be replaced individually with ease, offering excellent maintainability and a highly cost-effective solution.
Enhanced pH Calibration Convenience
The added detachable-cable design allows easy sensor removal for calibration, offering greater flexibility to suit different maintenance styles and improving both serviceability and work efficiency.
Sensors Selectable to Match Your Maintenance Style
- Improve the Efficiency of Routine Calibration and Maintenance NEW!
With the detachable-cable sensor, the sensor can be easily removed from the cable. By simply replacing the sensor with a pre-calibrated one on site and entering the setting data into the Analyzer, on-site cleaning and calibration are no longer required each time. This helps reduce the maintenance workload and lowers operational burden. - Quick Start-up at Installation for Improved Installation Efficiency NEW!
pH sensors with pH calibration setting data attached eliminate the need for initial calibration. Calibration work during on-site installation can be omitted, enabling quick and easy start-up. - Supports an Open System Architecture Through Digitalization
By combining pH and ORP sensor equipped with a built-in ID chip capable of storing calibration data with SENCOM Smart Adapter SA11, it becomes a digital sensor. Yokogawa provides open environment with higher model.

Key Benefits
- Suitable for a Wide Range of Applications
The sensor body is made of reinforced PPS engineering plastic, offering corrosion and heat resistance comparable to fluoropolymer (PTFE), while providing excellent mechanical strength. This robust design enables reliable use across a wide variety of applications. - Cost-effective, Long-term Use with Environmentally Friendly Design
Only the electrode components can be replaced, allowing long-term and economical operation while reducing environmental impact.
Replaceable parts include the glass electrode for pH sensors, the platinum (or gold) electrode for ORP sensors, and the liquid junction. There is no need to discard and replace the entire sensor body as long as it remains usable. - Reduced Maintenance Workload Through Flexible Operation Styles
Users can select the optimal configuration to suit their operational requirements, including detachable cables, sensors supplied with factory calibration setting data, and digital compatibility through combination with the SENCOM Smart Adapter SA11.By reducing calibration time, the solution contributes to a significant reduction in maintenance workload.
