Yokogawa SR20-AC32 pH Electrode

The Yokogawa SR20-AC32 pH Reference Electrode is a pressure-compensated reference electrode built for industrial pH measurement systems, using a bellows-type internal design to maintain stable electrolyte pressure and a steady reference potential as process pressures fluctuate. It features an Ag/AgCl reference with KCl electrolyte and a refillable electrolyte design for long-term service in harsh environments, with mounting compatibility for Yokogawa immersion, flow, and insertion holders. This electrode is intended for continuous use in high-purity and industrial liquid processes and is commonly deployed in power generation, high-purity water systems, pharmaceutical production, and chemical processing, especially when paired with a glass pH sensor and temperature probe to deliver reliable measurement in demanding applications.
