Product Overview
The SUP-ADE3300 conductivity sensor is designed for measuring conductivity and temperature in water-based processes. It is particularly suitable for pure water measurement, conventional water treatment, tap water monitoring, and conductivity measurement in thermal power plant water systems.
The sensor uses a contacting conductivity measurement principle. Its electrode structure detects the electrical conductivity of ions in the measured solution and converts this response into conductivity data.

Measurement Principle
The ADE3300 uses the contacting electrode principle for conductivity measurement. Two electrodes are positioned at a fixed distance from each other in the measured solution. When voltage is applied across the electrodes, ions in the solution move under the influence of the electric field.
Anions migrate toward the anode and cations migrate toward the cathode, allowing electrical current to pass through the solution. By measuring the resulting current and electrical resistance between the electrodes, the conductivity of the solution can be determined.
