9185 sc ozone analyzer

typical application

The ozone analyzer is suitable for ozone disinfection monitoring in drinking water, sewage, industrial process water and pure water industries.

 

Instrument characteristics

● Ozone analyzer adopts selective membrane electrode;

● No interference from PH, chlorine, bromine, chlorine dioxide or hydrogen peroxide in the sample;

● The process of replacing the membrane takes only a few seconds;

 

Detection principle

The detection principle of the ozone analyzer: O3 is reduced on the gold electrode (cathode): O3 + H2O + 2e-→ O2 + 2OH-

On the silver reference electrode (anode): silver is oxidized to: Ag +, reacts with bromide ion in the electrolyte: 2Br－ ＋ 2Ag → 2AgBr ＋ 2e－

The amount of reduction of O3 on the cathode produces a current proportional to the concentration of O3.
