Status
The SFC Series of analysers and controllers are discontinued and no longer available for sale. Limited services and spare parts support will be provided until January 22, 2028.

Description
The Wallace & Tiernan® Systems SFC analyzers & controllers are flexible measurement and control systems for disinfection and water chemistry control applications. Each SFC unit provides continuous measurement and control of a single water quality parameter (free chlorine, total chlorine, pH, ORP, conductivity, fluoride, temperature) and supports multiple measurement technologies via a single input. Units perform control functions adapted to the monitored parameter and application requirements.
