RC400G Residual Chlorine Analyzer

Brand: Yokogawa Electric Corporation

The RC400G residual chlorine analyzer employs a polarographic system that uses rotating platinum electrodes to provide continuous online measurement of residual chlorine concentration. 

By appropriate use of reagents, it is possible to separate residual chlorine (free chlorine + combined-chlorine) from free chlorine for measurement.

The RC400G is an intelligent residual chlorine analyzer that makes extensive use of microprocessors. Its design is based on the know-how gained through Yokogawa's many years of experience with residual chlorine analysis.
Features
  • Simple, one-touch calibration. Automatic sensor self-diagnostics (zero point, slope, response) during calibration.
  • Output range can be set in the field in case when the span is 1 mg/l or more. Remote switching 2-range capability is available.
  • Line-segment function available for output signal.
  • Simple verification of applied voltage/current characteristics (Plateau characteristic) between electrodes. Allows detailed knowledge of sensor characteristics for the target application to be obtained.
  • Improvements to rotating electrodes and glass bead cleaning have been added for even more effective automatic continuous cleaning.
  • Waterjet cleaning can be applied for the purpose of particularly dirty applications.
  • Easily maintained (easy-to-clean) cell construction.
  • Available for special version (for free chlorine measurement) designed to cope with very high concentrations of combined chlorine.
