Conductivity sensor is a kind of sensor used to measure the electrical conductivity or ionic concentration of ultra-pure water, pure water, drinking water, sewage. It is usually used in laboratory, industrial production and detection.

Global Conductivity sensor market was valued at 555.87 Million US$ in 2018 and is projected to reach 780.95 Million US$ by 2024, at a CAGR of 5.83% during the forecast period.

Conductivity Sensor has three types: electrode conductivity sensor, inductive conductivity sensor, ultrasonic conductivity sensor. The electrode conductivity sensor using the resistance measurement method, based on the electrolytic conduction principle. The inductive conductivity sensor using measure the liquid conductivity based on the electromagnetic induction principle. The ultrasonic conductivity sensor measures the conductivity according to the change of ultrasonic wave in liquid.
For electrode conductivity sensor, the key technology is the eliminating of the electrode polarization effect, capacitance effect and the production of electrical conductivity cell, so the future development direction would be the electrode material.
For the inductive conductivity sensor, the key technology is the check device, excitation voltage and the miniaturization of detector.
Both electrode conductivity sensor and inductive conductivity sensor is the most widely used conductivity sensor. To inductive conductivity sensor, it has the advantage of anti-pollution, corrosion resistance; it did not have the electrode polarization effect and capacitance effect. It has a Simple structure; it is easy to use. So, the inductive conductivity sensor is the trend of future development.

Key manufacturers in global Conductivity sensor market include: ABB, Omega, Hach, Mettler, Toledo, Emerson, Sea-Bird, Yokogawa, PASCO, Campbell Scientific, Global Water, Knick. Conductivity sensor key consumption markets locate at developed countries. The Europe takes the market share of 35%, followed by US with 32%. China consumption market has a quicker growing speed of CAGR 7.5%.
