FAQ

What is a refillable sensor and why would I choose it?

Refillable sensors have a port that allows manual replenishment of the reference electrolyte. Processes like pure water leach out out the electrolyte so the Ionotrode is a good choice. Other products like the ChemoTrode allow the for externally pressurized electrolyte so the process liquid cannot easily contaminate the sensor.

FAQ

What is the difference between ORP and Redox?

They are the same. Redox is a shortened word for “Reduction Potential”. ORP is shortened for “Oxidation Reduction Potential”. The sensor and measurement is the same.

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.
