Reliable Low Conductivity Measurement

Designed to excel in challenging conditions, pHure sensors deliver highly accurate pH measurement in pure waters. Stability of the reference diaphragm/junction potential provides monitoring consistency in low conductivity applications.

Faster Response, Simplified Maintenance

With a special glass membrane and an integrated temperature sensor, the pHure sensor ensures a fast, reliable response. Prioritize convenience by extending lifetime and minimizing maintenance with the internally pressurized gel electrolyte.

Increase Process Uptime

Leveraging ISM technology, seamlessly upload calibration data from lab to process for fast, error-free start-up. Achieve uptime and maintenance goals with predictive diagnostics on sensor calibration or replacement needs adapted to your process conditions.

High Measurement Stability

The pHure sensor’s controlled sample flow path with minimum volume reduces the accumulation of corrosion particles around the electrode membrane. A sealed stainless steel housing prevents contamination from air and provides electrical shielding.
