SEKO’s Sensor and Probes pH

pH, ORP, Electrical and Inductive Conductivity, Chlorine and disinfectants, Dissolved Oxygen, Turbidity and Flow

Monitoring a limit value or building a closed control circuit is easy with our sensors – in an enormous range of measuring applications. The measured values are delivered in real time and can be flexibly connected to the various process interfaces via bypass, immersion or installed fittings

Our product line provides a wide range of sensors for different measuring tasks. The field of application covers everything from simpler water treatment tasks to industrial process waters with more stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance.


pH measurement is based on the use of a pH sensitive glass electrode, a reference electrode and a temperature element to develops a potential proportional to the pH of the solution.

The reference electrode is designed to maintain a constant potential at any given temperature, and serves to complete the pH measuring circuit within the solution.

For every application up to 266 °F and 232 psi

Virtually maintenance-free

Highly accurate with pressurizable liquid electrolyte

Open hole, pellon or ceramic diaphragms
