The FC400G non-reagent free available chlorine analyzer adopts the polarographic method, using a rotating electrode to continuously measure online the concentration of free available chlorine.
The FC400G is a microprocessor-based, intelligent free chlorine analyzer whose development was based on Yokogawa's long experience with residual chlorine analysis.
The FC400G is intended for measurements in the water distribution network, at pumping stations, water delivery points, schools, and public facilities.
