This industrial-grade pH combination electrode features a sensitive glass membrane with low impedance, delivering fast response times, good thermal stability, and excellent reproducibility across the full 0–14 pH range. The Ag/AgCl gel electrolyte reference system provides a stable half-cell potential, while the ring PTFE membrane resists clogging for long-term online monitoring.
The electrode connects via a standard BNC connector and includes a 5 m cable for flexible installation. It outputs 0–5V linearly corresponding to pH 0–14 and is compatible with DFRobot Analog pH Meter boards (SEN0161, SEN0169) as a probe upgrade.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- BNC connector
- A twist-lock connector commonly used for probes, test equipment, and shielded signal cables. For pH and conductivity sensors, a BNC connector makes it easier to attach or replace electrodes without soldering.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
