IonoTrode pH Sensor
The IonoTrode pH sensor offers many unique features that make it well suited for high purity water measurement. The electrolyte can easily be added through the side-arm port or connected to an external storage container with 3M KCl solution. The F glass membrane has very low resistance which effectively reduces signal noise in low conductivity water. Finally the electrolyte flowrate from the sensor is easily regulated through a precision sleeve diaphragm which can easily be adjusted and cleaned in the event of clogging.

What is the expected lifetime of my pH sensor?
Expected pH sensor lifetime is dependent on the application. Exposure to strong chemicals, elevated temperature, fluctuating pressure, and solid build-up can all impact the sensor life. As the sensor ages, a sluggish response may become more apparent, and will require more frequent calibrations to compensate for this change. The overall health of the Arc pH sensors can be seen using the quality indicator in ArcAir software. Click to learn more about sensor lifespan and expiration in the Knowledgebase article. -
What solution should I store my pH or ORP probe in?
Hamilton recommends storing pH and ORP probes wet in either Hamilton Storage Solution (Ref 238931) or in 3M KCl solution. Click to see the pH/ ORP Sensor Storage and Regeneration Knowledgebase for more information. -
What is A-length and how is it measured?
A-length refers to the insertion depth of the sensor. It's generally measured from the base of the PG13.5 mounting threads but can vary with certain styles of sensors.
