What are the sensors commonly used in water quality detectors?

In today's more and more environmental protection, water quality analyzer is indispensable equipment for some occupations. Different occupations have different requirements for testing, so the corresponding operations of testing personnel are also different, and the selection of testing equipment is also different.

For example, most of the detection of industrial wastewater is heavy metal content. Drinking water plants may need to detect microorganisms, organics, heavy metals, disinfectants, and other parameters. The detection of these parameters is primarily completed by the various sensors of the water quality detector.

1. Residual chlorine sensor

Chlorine is the most widely used disinfectant, especially in the process of disinfection and disinfection of drinking water. The residual chlorine sensor can detect the content of free chlorine, monochloramine, and total chlorine in water samples.

2.TOC sensor

TOC is also called total organic carbon. It is an important target for analyzing organic pollution in water samples, and TOC sensors are also mostly used in water quality analysis in the pharmaceutical industry.

3. 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, an ultrasonic type according to the different measurement principles.

4. PH sensor

The PH sensor first obtains the pH value of the water body by detecting hydrogen ions, and the pH value is an important goal of the water body, and there are strict requirements for the water body's pH value in many occupations.

5. ORP sensor

ORP sensor is mainly used for the oxygen recovery potential of the solution. It can not only detect the water body but also detect the ORP data in the soil and culture medium. Therefore, it is also the sensor with the most application fields. Usually, it will follow Use of a PH sensor.

6. 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 waterbody data. Correct operation and use can help the inspector obtain more valuable data information.
