Hanna FC301B Solid-State Fluoride Ion Selective Electrode (Half-Cell)
The Hanna FC301B is a solid-state, half-cell ion selective electrode (ISE) specifically designed for measuring fluoride ions (F⁻) in aqueous solutions. With a rugged epoxy body, wide measurement range, and BNC connector, this electrode is ideal for water quality analysis, environmental monitoring, and educational or research laboratories. It requires a separate reference electrode for operation.
Features
Solid-State Sensing Technology for Fluoride Ion Detection
The solid-state membrane offers stable and selective response to fluoride ions, from saturation to 1 × 10⁻⁶ M (0.02 mg/L).
Delivers reliable results even in low-concentration fluoride samples.
Half-Cell Configuration for Flexibility
As a half-cell electrode, it must be used with a separate reference electrode, allowing flexibility to adapt to different testing setups and conditions.
Ideal Slope and Fast Response
Offers an approximate Nernstian slope of -56 mV per decade, providing accurate and fast readings in compliant pH and temperature conditions.
Durable Epoxy Body for Field and Lab Use
Built with impact-resistant epoxy, making it suitable for field testing or heavy-duty industrial and educational lab environments.
BNC Connector for Easy Integration
Comes with a 1-meter coaxial cable and BNC connector, allowing compatibility with most standard ion meters and pH meters with ISE input.
