Refillable pH Probes and Redox Probes

Refillable pH probes are the optimal pH sensors for extreme conditions. In combination with pressurized housings, these sensors will succeed in extreme applications where others would fail.

They can provide significant savings on replacement electrodes when properly maintained. A patented silver-ion trap prevents sulfides from poisoning the electrode, and the ability to refill the electrolyte means sensors can last for years.

Refillable pH probes offer you the ability to select the specific reference electrolyte suited to your application needs. KCl electrolyte offers a high outflow for improved diaphragm cleaning. Viscolyt has low outflow and therefore reduces refill intervals.

Calcolyt can be used where there is risk of calcium carbonate precipitation. The right electrolyte means better accuracy and reliability in pH Measurement.

pH electrodes with refillable electrolyte offer distinct features that safeguard measurement accuracy. pH sensors in this family offer a pressurized reference system that ensures permanent self-cleaning of the diaphragm, and some models include automatic temperature compensation with an integrated temperature sensor. Both of these features help to ensure constant, accurate measurement.

pH sensors in this family offer Intelligent Sensor Management (ISM®) technology to help ensure maintenance is only performed when needed.

The sensors provide you with an Adaptive Calibration Timer, measured in days, that indicates when you will next need to calibrate your pH sensor. This helps you to plan maintenance scheduling.
