IonoTrode Details

The IonoTrode pH sensor is specifically engineered for reliable pH measurements in ion-weak media and high purity water. Its unique features include an F glass membrane with very low resistance, which minimizes signal noise in low conductivity water. The sensor allows for easy electrolyte addition or connection to an external 3M KCl container via the side-arm port. 

The electrolyte flow rate is precisely regulated by an adjustable and cleanable sleeve diaphragm, ensuring optimal performance and longevity.

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.
