Conductivity Sensor Element

The conductivity electrode is a key sensor used to measure the conductivity, total dissolved solids (TDS) and salinity of aqueous solutions. It is widely applied in water treatment plants, environmental monitoring, aquaculture, boiler feed water, pharmaceutical production, food and beverage processing, as well as various industrial process water systems.

Featuring high sensitivity, fast response and excellent corrosion resistance, the conductivity electrode ensures stable and accurate measurement in long-term online operation. It supports a variety of installation methods, including immersion, flow-through and pipeline installation, and is compatible with most conductivity meters, controllers and multi-parameter water quality analyzers.

With a robust structure and low maintenance requirements, it provides reliable data support for water quality monitoring, process control and water purification management.

Precaution

1. The conductive electrodes come in two types: shiny and platinum-coated black. The purpose of the platinum-coated black is to increase the effective area of the electrode sheet and prevent and reduce electrode polarization when measuring the conductivity of solutions with high conductivity. Therefore, using platinum-coated black electrodes is more suitable.

2. Before using the platinum black electrode, it can be immersed in distilled water to prevent the black platinum from oxidizing. If the platinum black electrode malfunctions, it can be immersed in deionized water for 2 minutes, then cleaned with distilled water and measured.

3. If the platinum black coating peels off or fades, the platinum black needs to be re-electrified to ensure the accuracy of the measured data.

4. The electrode constant of the conductance cell marked on the electrode at the time of manufacture is only for reference. To verify the accuracy of the marked conductance cell constant, one can refer to the temperature and concentration of the standard solution being measured, look up the corresponding conductance C of the standard solution, and then calculate the conductance cell constant K based on the actual measured display value P of the conductance meter: K = C/P.
