Free Chlorine Total Chlorine Analyzer PACON 2501

The PACON 2501 on-line residual chlorine analyzer is an accurate, cost-effective and low-maintenance instrument for continuous on-line monitoring of residual chlorine. It detects the concentration of residual chlorine using the DPD colourimetric method and automatically adds reagents for colourimetric measurement, making it suitable for residual chlorine measurement during chlorination and disinfection and for monitoring residual chlorine concentrations in drinking water networks.

Product Features:

DPD colourimetric method for more accurate and stable measurements

Auto-diagnostics and auto-calibration

Built-in calibration curve

Low reagent consumption and easy replacement
