For the measurement of Fluoride , digital Fluoride meter is good option.

Zhihao Chen

You can try ion(F-)-selective electrode.

Hakim Lounici

Effectively the potentiometric method is the most appropriate you have to opt for a combined F electrode

Zhihao you are correct, this is by Fluoride selective ion electrode. Quick , economical and simple technique and easily accessible in market

Soheila Rezaitabar

Thank you every one for your suggestions...

Maria Anita Scorsafava

I also advise using a combined fluoride electrode using a Tissab II complexing solution to eliminate possible interferences.
