FAQ

Q1: How should the analog electrical conductivity sensor be maintained? ❯

Clean the electrode regularly to prevent fouling or scaling, especially when used in sewage or wastewater environments.

Q2: Can the conductivity sensor be submerged directly in liquid? ❯

Yes, it can be immersed as long as installation guidelines are followed and the housing/IP rating is respected.

Q3: Can the sensor detect very low conductivity? ❯

Yes, depending on the electrode constant, it can measure a wide range from low-conductivity pure water to higher-conductivity industrial solutions.

analog electrical conductivity sensor fits my application

Needed a conductivity sensor that could work directly with an analog input instead of adding another converter. The analog electrical conductivity sensor was a good match for the system. Wiring was not complicated, and the temperature compensation helped keep the readings more stable. It has been running outdoors for a while with no major issues.
