  • 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 effect of temperature on ORP?

Temperature compensation is a common requirement for accurate pH measurements, but not generally used for ORP. Why? pH is a measurement of the hydrogen ion concentration by the glass membrane. The voltage output of this glass membrane is temperature dependent, as is the hydrogen ion activity in the liquid. Temperature compensation will correct the pH voltage output back to a standardized 25°C. ORP differs from pH as it is not tied to a specific ion. The effects of temperature can be different depending on oxidizing and reducing substances present in the liquid. Due to this uncertainty, the ORP sensor output is uncompensated millivolts.

FAQ

What is ORP and why would I want to use it?

ORP is a measurement of the overall level of oxidizing or reducing substances present in the liquid. ORP is expresses as a millivolt (mV) signal. Positive voltage indicates an excess of oxidizing agents in the liquid. Conversely, negative voltage indicates an excess of reducing agents in the liquid. ORP is not specific to a single ion within the liquid but is often used to measure the status of a chemical reaction.

FAQ

What is a polymer-filled sensor and why would I choose it?

Polymer-filled sensors use solid (or nearly solid) electrolyte. This design keeps electrolyte from flowing out of the sensor and process liquid from poisoning or clogging the sensor. Polymer filled sensors are a great choice for industrial applications with strong chemicals, particulates and elevated pressures.
