Tips: How does the fluoride sensor work?

The fluoride sensor works by using an ion-selective electrode (ISE) that specifically responds to fluoride ions in the water. When fluoride ions come into contact with the electrode, they generate a voltage that is directly proportional to their concentration in the water. The sensor measures this voltage and converts it into a corresponding fluoride concentration, providing accurate and real-time data.
