EasyFerm Plus pH-Sensorfamilie
Die EasyFerm Plus-Sensorfamilie steht für hochwertige pH-Sensoren, die für anspruchsvolle Anwendungen in der pharmazeutischen Industrie ausgelegt sind. Diese Sensoren verfügen über einen speziellen Phermlyte-Elektrolyt und ein HP Coatramic Diaphragma, das in Verbindung mit dem druckbeaufschlagten Referenzdesign Verstopfungen und das Eindringen von Chemikalien aus der Prozessumgebung verhindern. Die Everef-F-Patrone sorgt außerdem dafür, dass der Referenzelektrolyt frei von Silber und Ausfällungen von Proteinen bleibt. Der EasyFerm Plus wird am häufigsten mit dem PHI-Membranglas kombiniert, da es chemisch sehr robust ist und Abweichungen in Anwendungen, in denen häufig eine Sterilisation, Autoklavierung oder SIP durchgeführt wird, stark reduziert.

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.

Warnings and Errors with Arc pH / ORP Sensors
The advanced diagnostics of Hamilton Arc pH / ORP sensors are indicated by warnings and errors. This article dives into the different types of warnings and errors as well as how they are defined. -
pH Calibration
The ever-changing nature of the electrochemical pH measurement requires that periodic calibration of the sensor is performed. The topic of calibration inevitably creates questions about the frequency and the procedure required to ensure the accuracy of the pH measurement.
