The ozone disinfection cabin, that is, people shake their clothes for half a minute after entering the ozone disinfection cabin, and at the same time, a relative concentration of ozone is released in the closed space, which can kill germs and viruses attached to people's clothing. From this, it can be understood that ozone has a certain role in helping the current epidemic.
Ozone has strong oxidizing property, and the killing rate of ozone on various bacteria, viruses, fungi, etc. is above 99.9%, without any toxic side effects, and will not cause drug-resistant bacteria. Its bactericidal ability is 600 times that of antibiotics, 1,000 times that of alcohol, 3,000 times that of chlorine and ultraviolet rays, and thousands of times that of chemical drugs and traditional Chinese medicine.
However, ozone has a strong irritant, and ozone can irritate the mucous membrane of the human respiratory tract.
When the ozone concentration in the air reaches 0.15ppm, it can be smelled.
When it reaches 0.5-1ppm, it can cause discomfort such as dry mouth.
When it reaches 1-4ppm, it can cause cough.
When it reaches 4-10ppm, it can cause a strong cough.
People cannot be directly exposed to high concentrations of ozone for too long (the safe concentration of ozone in the air stipulated by the Ministry of Health is 0.1ppm).
When using ozone for disinfection and sterilization operations, in order to avoid harm to people in the process, it is necessary to strictly detect the concentration of ozone in a closed environment to prevent excessive ozone concentration or ozone leakage. In order to avoid the harm of ozone, the disinfection of air must be carried out in a closed space and unmanned conditions, and it can only be entered after at least 30 minutes after disinfection.
▲ME2-O3-16×15 ozone sensor
In order to prevent the ozone concentration from exceeding the standard and endangering human health, it is necessary to use an ozone sensor for ozone concentration detection. Winsen Technology ME2-O3-16×15 ozone sensor adopts electrochemical principle and has the characteristics of low power consumption, fast response speed, high measurement accuracy, good stability and repeatability. It also responds well to low concentrations of ozone. When in use, it can be combined with the digital display mode to display the ozone concentration in real time, and can also set an alarm point to realize the intelligent application of ozone detection.
ME2-O3-16x15 electrochemical gas sensor is fuel cell type, which utilizes the electrochemical oxidation process of O3 gas on the working electrode. The current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
