YOKOGAWA SR20-AP24 PH ELECTRODE SR20AP24

Description:

The Yokogawa SR20-AP24 pH Electrode is used a non-flow reference electrode designed for industrial pH measurement systems. It provides a stable reference potential using a silver/silver chloride (Ag/AgCl) system with a thickened KCl electrolyte, ensuring accurate and stable readings in continuous process environments. The electrode features a PTFE diaphragm for improved resistance to fouling and contamination, making it suitable for standard industrial applications. 

Applications:

The Yokogawa SR20-AP24 is used in industrial liquid analysis systems for accurate pH measurement when paired with a glass electrode and temperature sensor. It is commonly deployed in water and wastewater treatment, chemical processing, and general industrial applications. The electrode is particularly suited for stable, non-flow measurement environments where consistent reference performance is required.
