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.
Features
- One-touch simple calibration.
- Output range can be arbitrarily set in the range of from 0-1 mg/l to 0-3 mg/l in the field.
- Line segment output is available for output signals.
- Easy confirmation of inter-electrode applied voltage/current characteristic (plateau characteristic). This allows understanding of the detailed sensor characteristics in the application.
- Rotating electrode/ceramic bead cleaning has been improved to realize further effective and continuous automatic cleaning.
- Easy-to-maintain (-clean) cell construction.
