Engineered with acid and alkali resistant glass, this electrode ensures stable pH monitoring in harsh industrial chemical processes and strong corrosive environments.

Specially developed low-impedance glass sensing bulb, delivers fast and stable response for low-conductivity pure water measurement.
Dot ceramic sand core diaphragm maintains steady reference potential, reduces contamination and extends service life.
PG13.5 thread design, convenient for installation in flow cells, immersion assemblies and industrial water monitoring systems.
The ASP121E pH electrode is optimized for online pH monitoring of pure water and low-conductivity water samples. Widely used in boiler feed water, deionized water, reverse osmosis and ultra-pure water systems in power, water treatment and pharmaceutical industries. It provides reliable continuous pH readings for low ionic strength aqueous solutions.
