GENERAL DESCRIPTION

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).

PRINCIPLE OF OPERATION

The determination of fluoride concentration is made according to double standard addition method. This technique enables an unknown concentration and the electrode’s slope factor to be determined simultaneously.

The Automatic Temperature compensation is available using HI 7662-T temperature probe. By setting the electrode isopotential point and enabling temperature compensation option in Setup menu, the obtained concentration is temperature compensated.

The accuracy of the obtained result depends on the stability of the mV reading in every step of the measurement.

Three selectable stability criteria can be selected in Setup menu. Select Medium or Accurate criteria in order to have accurate analysis.
