  overview

  Conductivity is an important parameter for measuring the conductivity of water. Water can conduct electricity because it contains ions, while pure water is non-conductive. Therefore, by testing the conductivity, the cleanliness of the water can be determined. By testing the conductivity of wastewater, the salt content of the wastewater can be determined. Similarly, by testing the conductivity of pure water, the cleanliness of the pure water can be determined. In addition, conductivity monitoring is also required in the food and pharmaceutical industry.

  rely on60Years of manufacturing experience,WTWWe can provide users with high-performance online conductivity testers and sensors. Our conductivity testers are widely used in sewage treatment, industrial process water, pure water, and ultrapure water fields, where you can seeWTWOutstanding achievements achieved. We have a quadrupole conductivity sensor with strong anti-interference ability and stable and reliable operation.

  Quadrupole testing technology

  By testing the conductivity of the electrolyte between two electrode plates(Reciprocal of resistance)Multiply by the electrode constant to obtain the conductivity of the solution. The conductivity sensor consists of two plates, and when alternating current is applied to the two plates, a current is generated between them, which is linearly proportional to the number of ions in the solution. The task of the host is to process the current signal transmitted by the sensor, combine it with the electrode constant, and finally convert it into a conductivity value for display.

  WTWThe quadrupole conductivity sensor has two additional plates, and no current flows between these two plates, only responsible for providing a stable and constant reference potential. When there is a change in the system, such as electrode contamination, the sensor automatically adjusts the voltage applied to the current plate based on the sensed signal, thereby achieving automatic background compensation.

  There are two advantages to the quadrupole method. Firstly, it completely solves the polarization problem during high conductivity testing; The second is to solve the problem of inaccurate readings caused by electrode contamination.
