Determination of ozone concentration parameters. Measurement of ozone concentration in water is carried out using one of the following methods: determination of the redox potential; photometry; application of amperometric sensors; titration. Instruments for measuring ozone in air use the following methods during operation: use of substances that chemically interact with ozone or its decomposition products; photometry; determination of the resistance of a number of metal oxides, etc. A specific method for measuring the concentration of ozone in water or air is determined by ease of use, frequency of reading, financial capabilities of the enterprise and a number of other factors.
