Milwaukee MA9011 Refilling Electrolyte Solution 3.5 M KCl

Milwaukee MA9011 Refilling Electrolyte Solution 3.5 M KCl is a premium, ready-to-use electrolyte specially formulated for refilling pH and ORP electrodes. Designed with 3.5 M Potassium Chloride (KCl) in high-purity distilled water, this solution stabilizes the reference system of your electrodes, ensuring accurate, reliable, and reproducible measurements in laboratory, industrial, and field environments.

Regular refilling of your electrode chamber prevents drift, slow response times, and erratic readings. The MA9011 solution maintains optimal ionic strength, keeps the junction flowing properly, and extends the lifespan of your pH/ORP probes — including double-junction electrodes.

Whether you’re conducting chemical analysis, environmental testing, water quality monitoring, research, education, or food and beverage quality control, this electrolyte solution ensures your sensors perform at peak efficiency.
