Ozone meter-The electrochemical ozone sensor can detect the concentration of ozone gas, and ozone is usually used in industries such as industrial production, disinfection and sterilization. What are the effects of specific applications in tap water disinfection?

In modern life, tap water has gradually become one of the indispensable survival guarantees in people's daily life. It is the water used for life and production that meets certain standards after a series of disinfection and purification treatments. The disinfection of tap water is directly related to the safety of human water, and also affects the health and safety of every human using tap water. There are usually many ways to disinfect tap water. Under the current circumstances, most of the water plants in my country usually use chlorine disinfection. Although the chlorine disinfection method has been continuously improving its methods, it still does not rule out the possibility of leaving harmful substances after chlorine disinfection. Therefore, people have begun to explore the search for safer disinfection methods that have less impact on human health. Ozone disinfection is one of the new disinfection methods.

Ozone is a light blue gas with a special taste at room temperature, and its chemical formula is O3, which is extremely oxidizing. Ozone has poor stability at normal temperature and pressure and can be decomposed into oxygen. If the human body inhales a small amount of ozone, it will be beneficial to human health, and if it is excessive, it will harm human health. Therefore, in the process of using ozone gas to disinfect tap water, it is generally necessary to use an ozone sensor to detect the remaining gas after disinfection to prevent the remaining gas with too high ozone concentration from harming the air environment and the lives and health of personnel.


Ozone meter-As a strong oxidant, ozone is second only to fluorine (F2) in oxidation. The sterilization and disinfection effect of ozone is mainly related to its strong oxidizing property and its ability to easily diffuse through microbial cell membranes. It can easily oxidize the organic matter of microbial cells or destroy the chain structure of organisms. Leading to cell death. Therefore, it has a strong lethality to tenacious microorganisms such as viruses and spores. According to scientific research reports. The sterilization effect of ozone is 1.5 times that of chlorine (Cl2). And the sterilization speed will be 600-3000 times faster than that of chlorine. In addition. Ozone usually does not produce harmful substances after disinfection treatment. Which can avoid "secondary pollution". Since the ozone manufacturing process usually only needs to consume electricity. The ozone used for disinfection of tap water can be obtained through on-site manufacturing.

In the process of using ozone disinfection to disinfect tap water. The use of electrochemical ozone sensors can monitor whether ozone gas leaks. And whether there is residual ozone gas and its concentration after disinfection. So as to detect in time and prevent ozone leakage from causing damage to human health. It can also be used to disinfect the exhaust gas to reduce the pollution of ozone to the air.

Ozone meter-In order to monitor the ozone gas concentration better and more accurately. Jingxunchangtong has specially developed and launched an electrochemical ozone sensor. The electrochemical ozone sensor uses electrochemical technology to measure the concentration of ozone in the air. When the gas enters the sensor, a chemical reaction occurs at the sensing electrode and a current is generated. The ozone gas concentration is further analyzed according to the value of the detected current.

Jingxuntong’s electrochemical ozone sensor reacts quickly and can accurately detect the concentration of ozone gas. The measurement data can be accurately measured to ppm level, the signal is stable, and the accuracy is high. The device adopts RS485 communication by default. Standard ModBus-RTU communication protocol. And can support customized 0-10V/0-5V/4-20ma/4G/NB-iot/LoRa/Ethernet/WiFi and other output methods. Which is convenient for users to choose and use Wire or wireless transmission of data. You can intuitively view the ozone concentration data on the computer webpage, mobile phone applet, mobile phone APP and other interfaces.
