Reliable online measurement of ozone – with DULCOTEST sensors.
To monitor or control clear water, for instance in the disinfection of potable water, there is the tried-and-tested standard ozone sensor type OZE3 mA. The innovative sensor type OZR1 can be used in polluted waters, e.g. raw water for potable water generation, cooling water and waste water. When monitoring for the absence of ozone, the active carbon filters indicate that ozone is getting through.
Features and Benefits
- Two application-optimised sensor types available
- Precise, real-time amperometric measurement for efficient process control (short response time)
- Amperometric measuring eliminates interference caused by turbidity or colouration
- Integrated temperature compensation eliminates interference caused by influence of temperature
- Diaphragm-covered electrodes for reduced dependence on flow, cross-sensitivities, substances in water and film-forming media
- Diaphragm-covered measuring electrodes embedded in an electrolyte ensure long service life. This maintains optimum measuring conditions regardless of process conditions
