Hanna Electrolyte Solution for Double Junction Electrodes (3.5M KCl)

The Hanna Electrolyte Solution for Double Junction Electrodes (3.5M KCl) is a high-purity, ready-to-use filling solution designed to maintain the stable reference potential required for accurate pH and ORP measurements. Formulated with 3.5M Potassium Chloride (KCl) in distilled water, this solution ensures optimal electrode performance, prevents contamination, and supports long-term measurement stability.

This electrolyte is specifically designed for double-junction electrodes, helping to maintain consistent flow through the reference junction while protecting the internal fill solution from sample interference. Its chemical stability at room temperature makes it ideal for routine laboratory work, field testing, and industrial measurements.

Whether you are conducting environmental testing, water treatment analysis, chemical manufacturing, food and beverage QC, or general laboratory pH monitoring, this KCl electrolyte solution ensures your electrode delivers precise, repeatable, and reliable readings.
