Conductivity. Conductivity is commonly used in ecology as a scalar to describe the ability of an electrolyte solution to conduct current. It is widely used. The unit of conductivity is Siemens per centimeter (S/cm), where 1mS/cm=1000S/cm.
The lower the conductivity, the weaker the EC and the worse the water quality. The higher the ion content, the stronger the conductivity of water, that is, the higher the EC .
K is the EC probe coefficient, where the lower the coefficient, the lower the EC range. However, the higher the unit accuracy, the higher the coefficient, the larger the range of EC , but the lower the unit accuracy.
Under normal circumstances, the EC of pure water is generally within 20us/cm. Therefore, the probe with K=0.01 can be selected. The conductivity of normal tap water or industrial water is within 200us/cm, so you can choose a probe with K=0.1. Because sewage contains more ions, the EC is relatively large, generally greater than 1000us/cm. Generally choose to use the probe with K=1. If there are some concentrated solutions, nutrient solutions, and salt solutions. Generally, the conductivity is greater than 10000us/cm, so you need to choose a probe with K=10.
Water conductivity detection is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water solutions. For the maintenance of equipment and facilities in industrial enterprises, digital EC sensors play an important role. The application of water ec sensor has brought great convenience to the maintenance of enterprise facilities.
The conductivity/hardness online analyzer is produced by the water quality sensor brand manufacturer. The instrument monitoring data is connected to the recorder through the transmission output to realize remote monitoring and recording. It can also be connected to the RS485 interface through the MODBUS-RTU protocol, which can be easily connected to the computer for monitoring and recording. At the same time, the device has 2 relay interfaces, which can set the alarm point output. The product is not subject to magnetic interference, does not consume probes, has high sensitivity, low detection limit, and long life. The probe adopts high-sensitivity, high-precision and high-performance electrodes, which have strong adaptability and simple maintenance; 2.4-inch LCD large screen high-definition display, real-time data display.
