Several sensors commonly used in water quality detection
Today, when environmental protection is increasingly valued, it is essential equipment for some industries. Different industries have different requirements for testing, so the corresponding operations of the testing personnel are also different, and the selection of testing equipment is also different. For example, industrial wastewater is mostly tested for heavy metal content. Drinking water plants may need to test for various parameters such as microorganisms, organics, heavy metals, and disinfectants. The detection of these parameters is mainly done by various sensors of the water quality detector.
Today we will introduce some commonly used sensors for water quality detectors:
1. Residual chlorine sensor
Chlorine is the most widely used disinfectant, especially in the sterilization and disinfection process of drinking water. The residual chlorine sensor can detect the content of free chlorine, monochloramine and total chlorine in water samples.
2. Conductivity sensor
The conductivity sensor can be said to be the most used sensing device in the water quality detector. It is mainly used to detect the concentration of total ions in the water body, and can be divided into electrode type, inductive type and ultrasonic type according to the different measurement principles.
The PH sensor mainly obtains the pH value of the water body by detecting hydrogen ions, and the PH value is an important indicator of the water body. In many industries, the pH value of the water body has strict requirements.
4. Turbidity sensor
The turbidity sensor measures the suspended solids in the water by measuring the amount of light passing through the water, and these suspended solids can reflect the pollution of the water body. Therefore, it is often used in the measurement of rivers, sewage and wastewater by water quality detectors.
In general, the sensor is an important device used by the water quality detector to measure water body data. Correct operation and use can help the inspector obtain more valuable data information.
