pH and ORP probes
pH-Wert (Wasserstoffionenkonzentration) und Redox-Wert (bzw. ORP: Oxidationsreduktionspotential) sind kritische Mess- und Steuerparameter in zahlreichen Prozessen. Hamilton Process Analytics bietet eine große Auswahl an pH-Sonden und Redox-Sonden für Bioprozesse und viele andere Branchen an, bei denen es auf eine hohe Genauigkeit und Zuverlässigkeit ankommt. Hamilton ist einer der wenigen Hersteller, die zahlreiche Optionen zur pH-Messung in den verschiedensten Ausführungen anbieten, so dass bei Bedarf auch Sensoren für ganz spezifische Anwendungen maßgeschneidert werden können.

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. -
How do I clean an ORP sensor?
The platinum band around the tip of the ORP sensor can oxidize over time. Light scrubbing with a mild abrasive such as toothpaste will remove the oxidization. Rinse with potable water and store in storage solution prior to usage

Comparing Glass Membrane Versus Optical pH Sensors
In biopharma applications there are two technology options for continuous pH measurement - glass membrane and optical. This article will explore both technologies along with their benefits and limitations. -
Principles of pH
pH has become a unit of measure so commonplace that it is now even referred to in consumer household products such as cosmetics, shampoo, and even food / beverage. It is important to ask - what are we actually measuring when we refer to pH?
