Features

Acid&Alkali Resistant Glass Membrane

The online glass pH sensor adopts special pH glass membrane with strong corrosion resistance, stable response in acidic and alkaline water samples.
Dot Ceramic Diaphragm&Gel Electrolyte

Dot ceramic sand core reduces blockage risk, gel electrolyte prevents liquid leakage and maintains stable potential.
PG13.5 thread, optional Cable Connection Type

Equipped with PG13.5 mounting thread, customers can choose one-piece cable or separable connector versions for different installation demands.

Application

This ASP120E online glass pH sensor is designed for continuous pH measurement in various water treatment applications. Thanks to its acid and alkali resistance and anti-clogging dot ceramic diaphragm, it works reliably for surface water, municipal wastewater and chemical process water monitoring. The PG13.5 thread and optional integrated or separable connector support flexible installation into flow cells, immersion assemblies and pipe fittings.
