The CS525 is a rugged pH probe suitable for just about any liquid pH-monitoring application, from laboratory to harsh field applications. The CS525 incorporates SENTRON’s high-tech, ion-sensitive field-effect transistor (ISFET) semiconductor as its pH-sensitive element.

ISFET is the most powerful pH-monitoring technology available today. This technology provides better measurements in extreme pH conditions. It allows the CS525 to monitor pH in liquids containing high solids, aggressive chemicals, or biological materials that would clog or contaminate the junction of the traditional glass-bulb pH probes.

The new probe's electronics are safely embedded in a durable PEEK body. Elimination of the glass bulb removes the possibility of broken glass, making the CS525 more durable and safer to use.
