4 Electrode Conductivity Sensor Digital With Automatic Temperature Compensation

The 4 electrode conductivity sensor measures the conductivity of the solution and the total ion concentration in the reaction solution. The 4 electrode technology has high reliability, no polarization. The conductivity sensor uses RS485 digital interface, standard Modbus communication, support access to the standard industrial control system.

It is widely used in general clean water, lakes and rivers, urban underground pipe networks and other environments.

Advantages Of The 4 Electrode Conductivity Sensor

• IP68 protection grade, can work continuously and stably underwater for a long time
• Strong anti-pollution ability, long-term online monitoring in harsh environments
• Quick response, accurate measurement, convenient operation
• Wide range, automatically switch the measurement range

Technical Data Sheet

4-electrode conductivity sensor measuring principle

The four-electrode conductivity cell is composed of 2 current electrodes and 2 voltage electrodes. The voltage electrode and the current electrode are coaxial. During the measurement, the liquid to be measured passes through the gap between the two current electrodes. An AC signal is applied to both ends of the current electrode. Through the current, an electric field is established in the liquid medium, and the two voltage electrodes induce a voltage to keep the voltage at both ends of the two voltage electrodes constant. The current passing through the two current electrodes has a linear relationship with the conductivity of the liquid.
