Component Specifications

Definition
An electrode pair is a critical component of conductivity probes, consisting of two precisely spaced electrodes that measure the electrical conductivity of liquids by applying an alternating current and measuring the resulting voltage drop across the fluid medium. These electrodes are designed for accurate, stable measurements in various industrial applications.
Working Principle
The electrode pair operates on the principle of conductive measurement where an alternating current is passed between the two electrodes submerged in a liquid. The conductivity is calculated based on the measured resistance between the electrodes, which is inversely proportional to the solution's ionic concentration and temperature.
Materials
Electrodes typically use platinum, stainless steel (316L), titanium, or graphite with insulating materials like PTFE, PEEK, or ceramic for housing and spacing. Electrode surfaces may be plated with platinum black for enhanced surface area and measurement stability.
