You Searched For: Desiccants

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.
