Reagentless Monitoring and control of chlorite! 
ProMinent® DULCOMETER® Chlorite analyzers provide precise monitoring or controlling of process variables for water and wastewater applications. DULCOMETER® products encompass a complete range of quality instrumentation from single channel transmitters to multi-channel disinfection controllers.

Gone are the days of expensive and time consuming laboratory analysis. The on-line process sample point for chlorite (patent pending) from ProMinent® directly monitors or controls the production of chlorite from water that is being treated with chlorine dioxide. Oxidation and disinfection using chlorine dioxide can lead to excess amounts of chlorite being generated as an unwanted by-product. The D1C Chlorite Analyzer from ProMinent® provides accurate and reliable analysis to keep your process within pre-determined values (EPA: 0.8 PPM) 24 hours a day.

Features and Benefits

  • On-line analysis of chlorite in real time with no reagents
  • Selective amperometric measurement with no cross-sensitivity to chlorine dioxide, chlorine or chlorate
  • Easy to install Chlorite packaged system
  • Not sensitive to fluctuations in temperature due to integrated temperaure compensation
  • Long sensor life due to diaphragm protected electrodes
  • Proven technology from ProMinent’s long line of amperometric sensors and D1C controllers
  • Simple calibration with DT4 test kit
