IonoTrode Details

IonoTrode is a pH sensor specifically designed for reliable pH measurement in ion-weak media and high-purity water applications. Building on Hamilton's proven pH sensor technology, IonoTrode provides accurate and stable pH measurements in low-conductivity samples where conventional pH sensors may struggle to deliver reliable results.

The IonoTrode utilizes a specialized F-glass membrane with very low resistance, minimizing signal noise and enabling accurate measurements in low-conductivity media. This design provides high measurement accuracy and long-term stability in applications involving ion-weak solutions and high-purity water.

The sensor allows for easy electrolyte replenishment and can be connected to an external 3 M KCl reservoir via the integrated side-arm port. An adjustable and cleanable sleeve diaphragm precisely regulates the electrolyte flow rate, supporting reliable sensor performance and extended service life.

Designed for demanding low-conductivity applications, IonoTrode combines specialized glass technology with flexible electrolyte management to provide dependable pH measurement over extended operating periods.

Common applications Water, Energy, & Environment, Water and Wastewater, Power Generation

Reduce costs with the refillable design, eliminating frequent sensor replacements.

Achieve long-lasting accuracy in low conductivity pure water measurements.

 Optimize performance with controllable electrolyte flow.

Refillable Electrolyte System

  • Refillable design allows manual replenishment of the 3M KCl Skylyte electrolyte via a convenient side-arm port, eliminating the need to remove the sensor for electrolyte replenishment and significantly reducing downtime and replacement expenses.
  • The side-arm can also be connected to an external storage container for continuous electrolyte supply.

Low Resistance F Glass Membrane

  •  The IonoTrode, equipped with an F glass membrane, exhibits very low resistance. This crucial feature makes the sensor particularly well-suited for measurements in low-conductivity water and weak-ion media.
  • The low resistance effectively reduces signal noise, ensuring the highest accuracy over a long period in these challenging applications
  • Hamilton pH sensors are characterized by their high measuring accuracy and long service life.

    Hamilton pH sensors are characterized by their high measuring accuracy and long service life. This contributes significantly to the control of our processes. They also help us to guarantee the required product quality and to further optimize processes.
