DULCOTEST® Sensors for Ozone

Measuring range 0.02 – 2 mg/l

Measuring ozone in oxidation and disinfection applications: DULCOTEST® sensors offer precise, reliable, application-specific measured values in real time.

Product description

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 Significantly less environmentally harmful by-products result from the generation and use of ozone ... more in the glossary 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 Significantly less environmentally harmful by-products result from the generation and use of ozone ... more in the glossary, the active carbon filters indicate that ozone Significantly less environmentally harmful by-products result from the generation and use of ozone ... more in the glossary is getting through.

Your benefits

  • Two application-optimised sensor types available
  • Precise, real-time amperometric measurement for efficient process control (short response time)
  • Amperometric measuring means no clouding or discolouration
  • Integrated temperature compensation eliminates faults 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

Field of application

  • Type OZE3: Swimming pool water, potable water
  • Type OZR1: Raw water, cooling water, industrial water, process water, waste water, ozone penetration monitoring
