Redox

Redox or Oxidation/Reduction Potential (ORP), unlike pH, is an absolute measurement expressed in millivolts and therefore redox sensing electrodes do not require calibration.

These standards act as control or reference materials not only to control the functionality of the sensing and reference electrode but also control the analyst’s technique, environmental conditions and the operation of the measurement meter.

We offer the widest range of values and pack options with all products certified with verifiable accuracy and uncertainty of measurement.
