200 mV Redox Oxidation/Reduction (ORP) Standard at 25°C

This 200 mV (± 5mV) Standard acts as a Control or Reference Material. This is because Redox Oxidation/Reduction (ORP) is an absolute measurement and the sensing electrode does not require calibration. This Standard verifies the functionality of the sensing and reference electrode; the analysts technique; environmental conditions and the operation of the measuring meter. The value of 200 mV quoted refers to the potentials of the platinum electrode v Ag/AgCl reference electrode.
- The produces a complete range of high-quality Redox Standards for the control; validation or qualification of Redox measurement.
- Very high specification (± 5mV).
- Manufactured to exacting specifications with an extended shelf life and stability; even after opening the bottle.
- All products are tested with proven verifiable accuracy and fully budgeted uncertainty of measurement.
