This ozone sensor is the one that you want to use to determine if the concentration of ozone (O3) gas in an indoor space is below the safe breathing limits. Ideal for professional ozone treatment providers who need to prove that they have aired out a property to safe levels. This sensor is for reading very low levels of ozone accurately. It is not intended for measuring high levels of ozone. For high level monitoring, find the "ozone detector" in our shop.
