Read water quality EC sensor


Water quality EC sensor measures EC in water. EC (Electric Conductivity) is the Chinese name for Conductivity, which refers to the ability of conducting current in a water body. In water quality monitoring, electrical conductivity is one of the important indicators to reflect water quality. When the conductivity value of water is higher, the conductivity is better, the TDS value of water is larger, TDS value represents the content of dissolved impurities in water, the greater the TDS value, indicating the content of impurities in water is larger, on the contrary, the smaller the impurity content of water, the lower the conductivity.

It can be seen that electrical conductivity plays an important role in water quality monitoring. Inspectors can preliminarily determine the water quality by the size of the conductivity, and then adopt different water treatment schemes.

In order to monitor the conductivity of water, we generally use water quality EC sensor, also known as water quality conductivity sensor. Water conductivity sensor as a professional measurement of the conductivity of solution monitoring instrument, often used in section water quality, aquaculture, sewage treatment, environmental protection, pharmaceutical, food and tap water and other aqueous solution conductivity value of continuous monitoring.

water quality EC sensor

Water quality EC sensor can be divided into electrode type EC sensors, inductive type EC sensors and ultrasonic EC sensors according to different measuring principles. Electrode type EC sensor adopts resistance measurement method according to the principle of electrolytic conductivity; Inductance EC sensor can measure the conductivity of liquid according to the principle of electromagnetic induction. Ultrasonic EC sensors measure conductivity according to ultrasonic changes in liquid. The first two sensors are widely used.

JXCT water quality EC sensor will use electrode type conductivity measurement method, built-in high-precision sensor measurement accuracy, the conductivity measurement range between 0 ~ 20000μS/cm, and the electrode constant is different to measure the range is also different: When the electrode constant K = 1, the measurement range is 0-2000 μs/cm, and the resolution is 0.1 μs/cm. When the electrode constant is K = 10, the measurement range is 10-20000 μs/cm, and the resolution is 1μs/cm.

EC sensor

The water quality sensor has two signal output modes: RS485 and analog. Built-in temperature sensor, with automatic temperature compensation function, can compensate the current temperature conductivity to the specified temperature. Can work in -20 ~ 60℃, relative humidity 0-85%, the product shell is IP65 protection grade can be used in outdoor rain and snow environment, has excellent anti-pollution ability, even in harsh environment can also long-term online monitoring, will not produce polarization.
