Free Available Chlorine Analyzer FC400G

*	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.
