pIon Fluoride Measurement
Highly-accurate Fluoride ion (F−) measurement for applications including semiconductor fabrication and glass manufacturing is now available with the S10 and S17 pIon Sensors from Electro-Chemical Devices (ECD, Irvine, CA) The S10 and S17’s specific (pIon) electrode cartridge measures the activity of “free” Fluroride ions in solution in concentrations from 0.02 to 2,000 ppm over a pH range of 5-8. Additional features include:
- An operational temperature range of 0 to 80ºC.
- Replaceable electrode cartridges, which can be selected to measure pH, ORP, dissolved oxygen, conductivity, and resistivity.
- Integration with ECD’s C22 Analyzer to provide automatic pH compensation and an advanced Multi-Bus architecture, which enables customization of up to four inputs and six outputs in a convenient ½ DIN NEMA 4X enclosure.
