Gas detector unit-Tap water is the domestic production water that reaches a certain standard after disinfection and purification. And it is a necessary guarantee for people's basic daily survival. The disinfection of tap water is directly related to the health and safety of each of our users. There are many ways to disinfect tap water.

And ozone disinfection is one of them. It is a relatively safer and more efficient disinfection method. When using ozone to disinfect tap water, an electrochemical O3 sensor is required to detect the disinfected exhaust gas to prevent the exhaust gas with too high ozone concentration from causing harm to the air environment and personnel health.

Ozone is a light blue gas at room temperature and has a special smell. Its chemical formula is O3, which is highly oxidizing. Ozone has poor stability at normal temperature and pressure and can be decomposed into oxygen by itself. Inhalation of this gas in a small amount is beneficial to the human body, while an excessive amount will cause damage to human health.

The sterilization effect of ozone is mainly due to its strong oxidizing property and easy diffusion through microbial cell membranes. Which can oxidize the organic matter of microbial cells or destroy the chain structure of organisms, leading to cell death. Therefore, it has great lethality to the stubborn microorganisms such as viruses and spores. Generally speaking.

The sterilization effect of ozone is 1.5 times that of chlorine. And the sterilization speed is 600-3000 times faster than that of chlorine. In addition, ozone will not produce harmful substances after disinfection. Avoiding "secondary pollution". Because the production of ozone only requires electricity. The ozone used in the disinfection of tap water can be produced on-site.

Electrochemical O3 sensor

In the process of disinfecting tap water with ozone. The electrochemical O3 sensor can monitor whether ozone is leaking and the concentration of residual ozone after disinfection. Preventing ozone leakage from harming the human body. And also contributing to the treatment of disinfection exhaust gas and reducing air environmental pollution .

Gas detector unit-The electrochemical O3 sensor adopts the electrochemical detection principle. By measuring the current generated when the target gas enters the sensor and a chemical reaction occurs at the sensing electrode. The concentration of the target gas can be detected.

The reaction is sensitive and the concentration detection is reliable. Wall-mounted waterproof shell, easy to install, high protection level. Using professional sensor probes for detecting ozone concentration. It can accurately measure ozone concentration, stable signal, high precision. And can adapt to various harsh conditions on site.

The electrochemical O3 sensor can be connected with environmental monitoring software. And the ozone sensor installed in the workshop can be remotely monitored and operated by the network administrator. The electrochemical O3 sensor uploads the collected data to the host computer of the manager. And displays it in real time on the software platform. So that the manager can understand the ozone concentration in the workshop in time. When the ozone concentration rises.

We can take appropriate measures to lower the temperature and increase the air humidity in order to reduce the ozone concentration in time. The manager can set different restrictions on the ozone sensor according to the actual situation. Once the ozone exceeds the standard. The platform will send an alarm message to the management staff as soon as possible to avoid the situation of high concentration causing harm to workers.
