PRELIMINARY EXAMINATION
The HI 84184 is a low cost, easy to use, fluoride ISE instrument that performs automatic analysis
with all the necessary calculations assuring to the user a simple and effective interface.
The instrument comes with a powerful and effective built-in algorithm to analyse the shape of the ISE
electrode response and to determine the reaction completion.
By simply pressing the Start key, the instrument performs automatic analysis, all the necessary
calculations and verifications. The result is immediately displayed in convenient units, then the
instrument is ready for another measurement.

SIGNIFICANCE OF USE
Fluoride ion (F
- ) comes from grapes used for wine and its usual concentration value varies between
0.1 and 2 mg/L. Higher levels of fluoride content in wine can derive from cryolite used by farmers
as an insecticide in the vine.
The HI 84184 ISE Fluoride meter measures the fluoride content in wine using an ion selective electrode.
The used method is double standard addition, and the result is readily displayed in F
- mg/L (ppm).
