Ozone
Where is it found?
Ozone (O3) is found in the troposphere and it is the result of the atmospheric reaction of a number of precursor pollutants, which come from both natural and man-ma- de sources. Precursor pollutants are originated by hu- man activities and include hydrocarbons and nitrogen oxides. They are largely emitted by cars and other vehi- cles, fossil fuel power plants, oil refineries, the agricultu- re sector and a number of other industries.

O3 cartridge
The Ozone cartridge has a built-in electrochemical sensor that detects NO2 and O3 concentration. Then, to measure accurately the O3 concentration, it is required to have installed in the same device the NO2 Cartridge. Thus, thanks to Kunak algorithm, it is possible to deliver accurate measurements of Ozone, with no NO2 influence, even at high temperature which are related to higher O3 concentration due to the sun radiation.
