Milwaukee MA911B/2 – Lab-Grade Double Junction pH Electrode with 2-Meter BNC Cable
The Milwaukee MA911B/2 is a professional, lab-grade double junction pH electrode engineered for demanding laboratory, industrial, and continuous monitoring applications. Its extended 2-meter (6.56 ft) BNC cable delivers exceptional reach for large tanks, deep vessels, and hard-to-access sample points—while the double junction design protects your reference system from contamination in the toughest sample matrices.
Why the MA911B/2?
Single-junction electrodes fail fast when exposed to heavy metals, sulfides, proteins, or high-ionic-strength samples. The MA911B/2's dual reference junction adds a critical barrier between the Ag/AgCl gel electrolyte and your sample, dramatically extending electrode life and maintaining measurement integrity where it matters most.
