9185 Ozone analyzer

Principle of Operation:

• 9185 sc ozone analyzer detection principle: O3 is reduced at the gold electrode (cathode): O3＋H2O＋2e－→O2＋2OH－

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

• The amount of O3 reduced at the cathode generates a current proportional to the O3 concentration.

Application Industries:

The 9185 sc ozone analyzer is suitable for ozone disinfection monitoring in drinking water, wastewater, industrial process water, and pure water industries.

Instrument Features:

• The online ozone monitor uses a selective membrane electrode;

• The online ozone monitor is not subject to interference from pH, chlorine, bromine, chlorine dioxide, or hydrogen peroxide in the sample;

• The online ozone monitor is easy to calibrate and maintain; the membrane replacement process takes only a few seconds.
