Honeywell 31117486-501 PH Cell

The Honeywell 31117486-501 is a specialized pH cell with Meridian electrode engineered for high-precision liquid analysis in demanding industrial cooling and boiler water systems. This industrial pH sensor replacement is built to maintain signal stability in high-temperature environments, operating effectively across a 10°C to 100°C temperature range. The integrated Meridian electrode utilizes a unique reference technology to resist fouling and poisoning, ensuring consistent electrochemical response even in high-purity or high-solids applications. Contractors will find the screw cap connector assembly straightforward for field installation, providing a moisture-resistant interface with standard instrumentation cables. As a genuine Honeywell OEM part, it ensures exact mechanical fitment and calibration compatibility with existing process controllers, reducing the risk of drift or hardware communication errors during critical system monitoring.

• Enhanced Thermal Tolerance: Rated for sustained operation up to 100°C, preventing premature sensor failure in hot process loops.
• Reduced Maintenance: The Meridian electrode technology minimizes reference junction clogging, extending the interval between calibrations.
• Secure Interfacing: The screw cap connector provides a robust electrical path and physical security against vibration.
• Accurate Calibration: OEM specifications ensure linear output and rapid response times for precise chemical dosing control.

Is the 31117486-501 compatible with standard Honeywell pH transmitters?
Yes, this cell is designed to interface with industrial series transmitters that accept the standard screw-type electrode connection and RTD compensation inputs.

How does the Meridian electrode differ from standard pH glass?
The Meridian design features a specialized reference path that is significantly more resistant to pressure fluctuations and chemical ingress than standard laboratory-grade electrodes.

Can this be used in freezing or sub-zero environments?
The operational range starts at 10°C; using this sensor in freezing conditions without heat tracing may damage the internal electrolyte and glass membrane.
