Contacting conductivity sensor can measure the conductivity value in water in real time, and has a wide range of applications. The sensing surface material of the contacting electrical conductivity sensor/probe for water adopts a double-cylinder structure of titanium alloy, which can resist the corrosion of most liquids. Low-noise cable directly leads out, 0~2000μs/cm measurement range, real-time response and accurate data. It is an ideal device for measuring water conductivity.

Tips: Contacting conductivity sensor vs. inductive conductivity sensor

1. Contacting conductivity sensor

• Principle: Directly contact the liquid through two or more electrodes (usually platinum or graphite), measure the current generated in the liquid after applying voltage, and calculate the conductivity.
• Advantage: High accuracy, especially suitable for measuring low conductivity (such as pure water). Fast response, stable data, simple structure and relatively low cost.
• Disadvantage: The electrode is easily contaminated or scaled and needs to be cleaned regularly. It is not suitable for corrosive or high-concentration solutions, has a limited life, and requires good maintenance to maintain measurement accuracy for a long time.

2. Inductive conductivity sensor

• Principle: Using the principle of electromagnetic induction, there are two coils inside the sensor (one transmitting coil and one receiving coil). When the conductive liquid passes through the sensor, the electromagnetic field induces a current in the liquid, which is then detected by the receiving coil and converted into conductivity.
• Advantage: Non-contact measurement, no electrode contamination or corrosion problems, suitable for measuring high-concentration, highly polluted, highly corrosive liquids (such as acid and alkali solutions), almost maintenance-free, long service life, can be used for continuous online monitoring, strong anti-interference ability.
• Disadvantage: Not suitable for low conductivity liquids (such as ultrapure water), high cost, and usually larger in size than contact sensors.
