Electrodes & Probes

Explore a range of laboratory electrodes and measurement probes designed for use with pH, conductivity, dissolved oxygen and other electrochemical measurement instruments.

Our electrode range includes pH electrodes, conductivity electrodes, dissolved oxygen (DO) electrodes, ORP electrodes, ion-selective electrodes (ISE) and related replacement probes and sensors. These electrodes are available in different designs and specifications to suit various laboratory instruments, sample types and measurement applications.

pH electrodes are used with pH meters to measure the acidity or alkalinity of aqueous samples. Different electrode designs are available for general laboratory use and specific sample conditions. Conductivity electrodes are used to measure the electrical conductivity of solutions, while DO electrodes and probes measure dissolved oxygen in water and other aqueous samples.

Specialised ORP electrodes are used for oxidation-reduction potential measurements, while ion-selective electrodes are designed for measuring specific ions in suitable sample solutions.

Electrodes are commonly used in water quality testing, environmental analysis, chemical laboratories, pharmaceutical applications, food and beverage testing, research, education and industrial quality control.

When selecting an electrode or probe, consider instrument compatibility, measurement parameter, measurement range, sample characteristics, electrode material, connector type, temperature requirements, calibration method and intended application. Proper storage, cleaning, calibration and maintenance are also important for maintaining electrode performance and measurement reliability.
