Electrolyte Solution, 3.5M KCl + AgCl, 4 x 30 mL

Product Overview

HI-7071 Electrolyte Solution, 3.5M KCl + AgCl, 4 x 30 mL bottles

HI-7071 is a pH and ORP Electrode Fill Solution containing 3.5M Potassium Chloride (KCl) plus Silver Chloride (AgCl), available in a 4 x 30ml bottles, specifically made for single junction electrodes.

Useful information:

pH and ORP electrodes are available with a single junction or double junction reference cell. The single junction reference electrode is made with a silver (Ag) wire coated with silver chloride (AgCl). This wire is in contact with the sample to be measured by a fill solution which flows through the junction. In single junction electrodes, this fill solution is 3.5M KCl with AgCl which ensures optimum measurement performance from the single junction pH or ORP electrode.

Double junction pH and ORP electrodes will require 3.5M Potassium Chloride refill (HI-7082), because it has two chambers. The inner chamber has the Ag/AgCL reference wire with a fill solution of KCl plus AgCl, while the outer chamber has a KCl fill solution providing a Silver-free solution. This is important as Silver can precipitate easily in the presence of heavy metals and block the outer reference junction resulting in a longer response time and poor performance.

Hanna electrolyte fill solutions are made using high quality reagent-grade chemicals and are manufactured to the highest standards for precision and accuracy.
