FAQs -More information about ozone sensors
Ozone is a well-known gas. Ozone is often present in the atmosphere, helping to filter harmful rays from the sun and allowing the earth’s organisms to thrive. In the medical field, ozone can also be used for disinfection. In the state of pure ozone, it can carry out effective disinfection and sterilization, but it must be cleaned up afterward to avoid pollution. Inhalation of ozone in a small amount is beneficial to the human body, but a large amount of inhalation will be harmful to the human body and will be chemically converted into VOC pollutants at a specific temperature. Ozone treatment and detection have also become one of the key tests of environmental protection.
An o3 sensor is an electronic device used to monitor the concentration of ozone in the air. The built-in ozone detection module converts the ozone concentration into an electrical signal and outputs it.
According to different places of use, our company provides four kinds of ozone sensors: home ozone monitor, portable ozone detector, duct type ozone detector, and fixed ozone detector.
veswe is a large-scale sensor manufacturer integrating R&D, production, and sales, with 15 years of production experience. The industrial gas sensors produced are sold at home and abroad and have many agents. We have advanced technology and an R & D team, can provide users with customized services.
