AMI Codes-II O3 – Continuous Monitoring of Dissolved Ozone in Water Treatment
Ozone is widely used as a powerful disinfectant in water treatment and hygienic processes. To ensure effective operation and safe residual levels, ozone concentration must be monitored continuously.
The SWAN AMI Codes-II O3 analyzer provides reliable online measurement of dissolved ozone (O₃) in water. This allows operators to control ozone dosing precisely, ensuring effective disinfection while preventing excess oxidant in the system.
Using a colorimetric photometric measurement method, the analyzer delivers accurate and stable monitoring for demanding water treatment and process applications.

Reliable photometric ozone measurement for process control
The AMI Codes-II O3 analyzer measures dissolved ozone using a colorimetric reaction method.
During the measurement process:
- A reagent is automatically added to the water sample.
- Dissolved ozone reacts with the reagent to produce a measurable color change.
- The integrated photometer determines the ozone concentration based on the color intensity.
The analyzer automatically controls the measurement cycle, ensuring consistent results and reliable long-term monitoring.
Key features supporting stable ozone monitoring
- Continuous online measurement of dissolved ozone (O₃)
- Accurate photometric colorimetric measurement technology
- Automatic reagent dosing and measurement cycles
- Integrated photometer for stable measurement results
- Adjustable measurement intervals to optimize reagent consumption
- Automatic zero calibration for long-term stability
- Sample flow monitoring and reagent level monitoring
- Industrial communication interfaces for process integration
These capabilities allow operators to maintain stable ozone dosing and reliable disinfection control.
Applications where ozone monitoring ensures safe process control
The AMI Codes-II O3 analyzer is used in systems where ozone is applied as a disinfectant or oxidizing agent.
Typical applications include:
- Pharmaceutical water systems – monitoring ozone used for sanitizing purified water loops
- Drinking water treatment plants – ozone disinfection and oxidation processes
- Food and beverage production – hygienic process water treatment
- Industrial water treatment systems – oxidation and advanced treatment processes
- Public water facilities and swimming pools using ozone as secondary disinfection
Continuous monitoring ensures that ozone levels remain effective for disinfection while preventing overdosing and unnecessary chemical consumption.
