Polyplast Pro pH and ORP Sensors
The Maintenance free Polyplast Pro sensor is designed for pH measurement in water applications, especially in low conductvity samples, e.g. wastewater, fish farming, ground water, etc.
The Single Pore liquid junction guarantees best measurement results because of direct contact between the sample and the Polisolve electrolyte - clogging is nearly impossible. the Polyplast Pro sensor comes with a robust plastic shaft and glass bulb protection.

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.
