Redox/ORP Standards
Since all analytical instruments require calibration, the redox and ORP standards were specifically designed to verify that reduction potential electrode sensors are functioning correctly. Once oxidizers and reducers are reset to match the known solution levels, personnel can effectively test chemicals for acquired or released electron affinity after a reaction. Commonly used in water quality testing, redox and ORP standards increase result reliability for proper treatment determinations in controlling disinfections.
VWR®, Redox (ORP) Standards
Supplier: VWR Chemicals
Avantor offers a wide range of REDOX (ORP) standards, which are produced from high quality reagents.These reference materials can be used as control standards to check the functionality of both the elextrodes and the measuring instruments. The values are temperature dependent, so it is important to control the environment of the measurement. A table of temperatue and corresponding Redox value is available on both the label and the batch specific certificate.
