Combination Electrodes for pH, ORP & Titration | Refillable, Gel-Filled, Epoxy, Glass & Specialty Probes

Achieve accurate, stable, and reliable electrochemical measurements with our premium range of combination electrodes, specifically designed for pH, ORP (Redox), and titration applications. Suitable for use in laboratory, industrial, environmental, food, and pharmaceutical testing, our electrodes provide high precision and long service life under diverse conditions.

Our collection includes refillable and sealed (gel-filled) combination electrodes, single and double junction models, and specialty electrodes for high temperatures, low ionic strength samples, viscous or particulate-rich solutions, and non-aqueous solvents. Choose from rugged epoxy-bodied designs for field and food testing, or classic glass-body electrodes for general laboratory use and high chemical resistance.

Engineered for compatibility with all major pH and electrochemistry meters, these probes are ideal for manual and automated titration setups, water quality monitoring, laboratory research, quality control testing, and more. Select from electrodes with integrated temperature sensors, replaceable reference elements, and screw cap or BNC connectors for seamless lab integration.

Enhance electrode performance and lifespan with our full range of storage solutions, electrode cleaning solutions, reference electrolytes, and calibration buffers, ensuring dependable readings and regulatory compliance.

With rapid UK shipping, expert technical support, and trusted ISO-certified quality, our combination electrodes deliver consistent, high-quality performance across all your pH, ORP, and titration needs.
