Fluoride (F⁻) Ion Selective Half-Cell Electrode PF-2-01

Overview

The fluoride ion selective electrode PF-2-01 is a half-cell (indicator) electrode. It carries a crystal membrane sensing element in a polycarbonate body. Specifically, it measures F⁻ from 1 × 10⁻⁶ – 0.1 M (19 µg/L – 1.9 g/L) at 5 – 45 °C and a working pH of 4 – 8. However, OH⁻ interfere.

Because it is a half-cell, you use it together with a separate reference electrode. The manufacturer specifies: 232–01. In addition, the BNC(Q9) connector fits benchtop ion meters and titrators with separate indicator and reference inputs. As a result, you can choose the reference system and the outer filling solution to suit your sample.

Applications

This electrode serves drinking-water fluoridation control and SANS 241 compliance checks, industrial effluent, and QC of toothpaste, food and pharmaceutical products. Therefore, calibrate it with standards that bracket your sample for accurate results. In addition, keep sample and standards at the same temperature.

Why buy the fluoride ion selective electrode from Hadron Group

Hadron Group runs its own water laboratory in Pretoria. In addition, we supply analytical instruments to municipal, mining, food and industrial laboratories across South Africa and the SADC region. We stock the electrodes we use ourselves. Moreover, calibration standards, filling solutions and replacement membranes are available for every model. Finally, we help you match the electrode to your meter before you order.

Frequently asked questions

How do I order the fluoride ion selective electrode PF-2-01? Quote the model number and your meter. In addition, tell us which standards and filling solutions you need, and we will quote the set.

Do I need a reference electrode? Yes. This is a half-cell (indicator) electrode. The manufacturer specifies 232–01. In addition, we can pair it for you when you order.

Which meters is it compatible with? In short, benchtop ion meters and titrators with a BNC(Q9) indicator input and a separate reference input.

What is the measuring range in concentration units? The range is 1 × 10⁻⁶ – 0.1 M. In other words, it corresponds to 19 µg/L – 1.9 g/L.
