SUCH conductivity water sensor measures conductivity from 0.1~500mS/cm, TDS up to 60000ppm, and salinity up to 500ppt with 1μS/cm resolution. It uses separated excitation and sampling electrodes to avoid polarization deviation and reduce AC errors, while its flat structure improves fouling resistance and cleaning convenience. Built with corrosion resistance and wide measurement capability, conductivity sensor delivers accurate and stable performance for long-term water quality monitoring.
Note: Default front G3/4 thread, optional front and rear G3/4 threads (contact us).
An inductive conductivity sensor, also called a toroidal or electrodeless conductivity sensor, measures the conductivity of a liquid without direct metal-to-liquid contact. It uses two coils encapsulated in a non-conductive body. One coil generates an alternating magnetic field that induces a current in the liquid, while the other coil detects the resulting signal.
Inductive sensors have no exposed electrodes, so they are resistant to fouling, scaling, and corrosion. They require minimal maintenance, have longer service life, and perform well in harsh environments such as high concentrations of acids, bases, or salts. They are also not affected by electrode polarization, which improves measurement stability.
They are ideal for high-conductivity liquids such as concentrated acids (HCl, H₂SO₄), caustic soda, brine, seawater, and chemical wastewater. They are less suitable for very low-conductivity liquids (like ultrapure water) because the induced current is too weak to measure accurately.
