Tips: Fluoride ion selective electrode working principle

The fluoride ion-selective electrode (ISE) operates based on the Nernst equation, which describes the relationship between the concentration of an ion in solution and the voltage across the electrode. The ISE consists of a solid-state membrane selective to fluoride ions, typically made of lanthanum fluoride crystals. When immersed in a sample solution, the fluoride ions in the sample interact with the membrane, generating a potential difference. This potential is measured against a reference electrode, and the Nernst equation is applied to determine the fluoride ion concentration. The electrode's selectivity is crucial, ensuring minimal interference from other ions. The fluoride ISE finds applications in water quality monitoring, particularly in assessing fluoride levels for public health and environmental purposes.

Real-time measurement

Can this sensor measure in real time? Can I connect it to an Arduino or an ESP32?

ATO Responded

Sorry, the default output interface for this fluoride ion selective electrode unit is BNC (Q9), and it cannot be directly connected to an Arduino or an ESP32. It is generally used directly with online fluoride ion monitors and water quality controllers.

Precise, durable, and affordable

I’ve been using the fluoride ion selective electrode for my water quality testing, and it works very well. The readings are accurate and stable, making it reliable for routine fluoride monitoring. It’s easy to connect with a reference electrode and responds quickly to changes in concentration. The build quality feels solid, and it performs consistently even after multiple tests.
