Scientific Citations

  • We particularly appreciated the professional and personable approach.

    The training on pH sensors was highly beneficial for us. After a detailed introduction to the fundamentals of pH measurement, electrode measurement principles, and the topic of troubleshooting/prevention, we had sufficient time to ask our specific questions. This enabled us to apply what we learned immediately and integrate it directly into our laboratory routine. We particularly appreciated the professional and personable approach of Mrs. Näf-Rüdiger, who guided us through the informative and application-oriented training session.

FAQ

What is the Everef F Reference System?

The Everef-F reference system uses a silver ion barrier to separate the reference element from the electrolyte. This design prevent Ag+ precipitation from occurring and clogging the diaphragm. It is a perfect design for applications with proteins or sulfides in the process liquid.

FAQ

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.
