Economical Guaranteed Quality 201 1 Economical Online Measurement Fluorine Electrode

1

Application field:

The electrode is used as an indicator electrode, an electrochemical sensor used to measure the concentration of fluoride ion or
lanthanum ion in the solution. It can indirectly measure elements such as silicon, aluminum, iron, calcium, magnesium, thorium,
and lithium. The electrode is a bonded structure

Matters needing attention:

1. Before using the electrode, it needs to be soaked in 10-3M NaF solution for 1-2 hours, and then repeatedly washed with
deionized water until the blank potential value reaches about +270mV. 2. Do not rub the electrode chip with hard objects. If there
is any oil stain, wipe it with alcohol cotton ball first, and then wash it with deionized water. 3. After the electrode is used,
it should be cleaned to the blank potential value and stored. 4. The filling solution in the electrode is a saturated solution
containing 10-3M sodium fluoride and silver chloride, and 10-1M sodium chloride.
