Dissolved Ozone Analyzers

Ozone decays quickly after dosing, often within minutes, so a sample taken away from the process no longer reflects the actual residual at the point of use. A continuous inline reading is the only reliable way to confirm the disinfection level and adjust dosing before it drops too low.

It's a membrane amperometric probe: dissolved ozone diffuses through a microporous membrane and reacts at an internal electrode, producing a current proportional to concentration, with a built-in temperature sensor for automatic compensation, the same principle as Chemitec's other oxidant sensors.

Yes. The Series 46 transmitter displays the ozone reading, raises alarms and can control the ozone generator output, with one or two parameters, so the dose tracks the measured residual instead of running the generator at a fixed rate.

Yes. The Series 46 handles two parameters on one display, so ozone and pH, or ozone and another compatible parameter, can share a single transmitter instead of needing two separate controllers.

Common applications are bottled water and beverage rinse water, drinking water disinfection, and cooling water or process water treatment, wherever ozone is dosed and its fast decay means the residual needs continuous confirmation rather than periodic sampling.

The S494 N ozone sensor is rated 0 to 3 bar and 0 to 45 °C as standard, in PVC, PEEK or AISI 316 construction depending on the version, which covers most bottling, drinking water and cooling water applications without special conditioning.
