Medical equipment ultraviolet lamp tube

When using ultraviolet light, you can close the doors and windows, and no one can be indoors. Turn it on for half an hour, then turn it off, and then wait 1-2 hours before entering, so it won't be strange. Low concentration ozone smells like grass. Because people are very sensitive to ozone, normal people will smell it at 0.0 1PPM. Some tube materials of ultraviolet lamps produce ozone when they irradiate air. Food processing plants use ozone generated by ultraviolet lamps for air disinfection and equipment disinfection.
