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 analysed analogically to the pH measurement.
Application Areas
Typical application areas of the Fluoride Sensors are waterworks in those countries, where Fluoride is dosed into the drinking water for caries prevention purposes and continuous measurement is applied as means of control.
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 realtime-measurement
- Long-term stable measurement
- No additional conditioning chemicals (e.g. TISAB) necessary
- Easy calibration by means of complete Photometer-Kit (Type DT2)
