Accurate fluoride-ion measurements are required for applications including semiconductor fabrication and glass manufacturing. The S10 and S17 Fluoride pIon Sensors (photo) measure the activity of free fluoride ions in solution in concentration from 0.02 to 2,000 ppm over a pH range from 5–8. They operate over a temperature range of 0 to 80°C. The sensors can be integrated with the company’s C22 Analyzer to provide automatic pH compensation. — Electro-Chemical Devices, Inc., Irvine, Calif.
