Is the fluoride ion meter an accurate measure of fluoride?
Thread Content
This year, our factory has equipped itself with a fluoride ion meter, which is currently in trial use!
Just take the same sample for external testing and you’ll know.
The determination of fluoride ion content using a fluoride ion selective electrode is highly reliable, with accuracy and repeatability that are acceptable to most people. Samples with high concentrations can be analyzed directly by potentiometric method, while samples with low concentrations and those containing possible interfering components can be determined using the single or double standard addition method.
Fluoride ion-selective electrodes are very reliable.
