Features

Accurate pH readings across water and process applications

The combination electrode and automatic temperature compensation provide stable readings of weak potential signals. Corrosion-resistant housings and flexible mounting cover applications from ultrapure water to wastewater.

Advanced Circuitry

High-impedance input, high-precision acquisition of weak pH potential signals, anti-electromagnetic interference.

Easy Installation

Submersion / flow-through / threaded insertion options, standard 5m cable for quick deployment.

Industrial-grade Protection

IP68 full protection, POM / 304L / PPS corrosion-resistant housings for different scenarios.

Fast Response

Fast response, automatic temperature compensation, stable readings, low drift, low maintenance.
