DULCOTEST® Fluoride Sensors

Graduated measuring ranges 0.05 – 100 mg/l

Accurate measurement of fluoride with DULCOTEST® sensors in the monitoring of potable water and waste water, suitable for pH values up to 9.5.

Product description

Reliable online measurement of fluoride – with DULCOTEST® sensors

In some countries fluoride is monitored when potable water is fluoridised, but also generally during the treatment of industrial waste water.

Our product line of DULCOTEST® fluoride sensors provides two types of sensor, optimised for these applications.

The sensor consists of a fluoride transducer, the connectable transducer of a reference electrode and a separate temperature measuring unit. The sensor is based on the potentiometric measuring principle with the help of an ion-selective electrode (ISE) and a reference electrode.

The measuring point is available fully mounted on our measuring and control system DULCOTROL® with the sensor fitting and controller DULCOMETER® diaLog DACa.

Your benefits

  • Precise, real-time potentiometric measurement for efficient process control (short response time)
  • Can be used up to a pH of 9.5
  • Selective LaF3 crystal eliminates faults caused by cross sensitivities
  • Rapid external temperature compensation eliminates faults caused by influence of temperature
  • Potentiometric principle prevents faults caused by flow changes
  • Potentiometric measuring principle enables quick commissioning

Field of application

  • Monitoring of fluoride in potable water. In some countries it is standard practice to add fluoride to drinking water to prevent tooth decay.
  • Monitoring discharger limit values in industrial waste water, e.g. in the semiconductor industry
