DULCOTEST® Fluoride Sensors


Fluoride Measurement

The Fluoride Sensor is a potentiometric sensor working with ion selective electrodes (ISE) and a reference electrode supplying the measurement signal (mV).

Basic Principles for the Measurement of Fluoride in Aqueous Solutions

Potentiometric determination of the Fluoride concentration is effected analogically to pH measurement. Instead of a glass diaphragm, a LaF3 single crystal is used. Thus, selective penetration of Fluoride Ions in the interior of the electrode is enabled. Here, the concentration-dependent potential is measured against the reference electrode as voltage and analyzed analogically to the pH measurement.

Application Areas

Typical application areas of the Fluoride Sensors are Water treament generators, where Fluoride is dosed into the drinking water for the prevention of cavities and continuous measurement is applied as means of monitoring.

Our Program offers the following Advantages:

  • For easy and fast installation, Fluoride sensors are only offered as ready for operation and mounted on PE-panels, i.e. plug & play with optimally inter-adjusted components.
  • Exact and reliable real-time measurement
  • Long-term stable measurement
  • No additional conditioning reagents (e.g. TISAB) necessary
  • Easy calibration by means of ProMinent's complete Photometer-Kit (Type DT2)

 

The Fluoride Electrode is an ion-selective Sensor based on the potentiometric measuring principle, determines and monitors the concentration of the anion Fluoride in the fluoridation of drinking water. The corresponding frame conditions must be observed.

Advantages

  • Efficient process monitoring through precise potentiometric real-time measurement (short response times)
  • No cross sensitivities or interference due to the use of a selective LaF3-crystal
  • Minimal temperature influence due to extraordinarily fast external temperature compensation
  • Potentiometric principle minimizes disturbances due to flow changes.
  • Operating pH range 5.5 to 8.5
  • No additional conditioning chemicals (e.g. TISAB) necessary.
  • Ease of commissioning due to potentiometric measuring principle
  • Long sensor; life due to patent-pending inner electrodes.
  • Easy calibration by means of a complete photometer kit (type DT2) is available
  • Short delivery times allows for rapid replacement
  • Private labeling and price allowance for OEM partners

 

 

Housings

DLG IV in-line sensor housing
