Measure free fluoride ions in aqueous solutions quickly, simply, accurately and economically with the Thermo Scientific™ Orion™ Fluoride Electrodes. The Thermo Scientific™ Sure-Flow™ junction allows easy cleaning and is easy to use in tough samples.The half-cell electrode requires a separate reference electrode. We recommend the reference electrode 900100 to be used with the half-cell electrodes 9409BN and 9409SC


The measurement of fluoride in drinking water using an ion selective electrode is an approved ASTM method: ASTM D 1179 A separate reference electrode is unnecessary with the combination fluoride electrode, making it convenient to use with small sample volumes.

  • Free-flowing Sure-Flow junction assures stable, drift-free potentials.
  • When conventional electrode junctions clog, the Sure-Flow junction can be opened and flushed clean simply by pressing the cap.
  • Fluoride Half-Cell Electrode used in conjunction with the Orion 900100 Single Junction Reference electrode offers the benefits of the Sure-Flow junction design:
      • Calibration standards catalog number: 940906 — 0.1 M NaF; 940907 — 100ppm F-; 040906 — 1ppm F- with TISAB II; 040907 — 2ppm F- with TISAB II; 940908 — 10 ppm F- with TISAB II
      • Required ISA catalog number: 940909 — TISAB II; 940911 — TISAB III
