R3.256F - BWB+ISI 12mm Fluoride Ion Measuring Combination Electrode - Technical Data Sheet

Introduction

The BWB+ISI R3.256F Fluoride Ion Measuring combination electrode is a robust, high performance 12mm electrode constructed from an inert polymer material which incorporates an ion sensitive membrane. The membrane is a crystal of Lanthanum Fluoride which produces a potential proportional to the amount of fluoride ion in the solution. The Fluoride ion is complexed with hydrogen below pH5 and the electrode is subject to hydroxide interference above pH8, therefore accurate measurements can only be made between pH5 and pH8.
