Series of On-line Titrimetric Analyzers

Titration involves determining the analyte(s) of interest by the addition of accurately known volumes of standardized titrant to a sample solution. The TitriLyzer™ Series of On-line Titrimetric Analyzers are state of the art titration systems equipped with a high precision dispenser system and other quality components, available at an attractive price/quality ratio.

For the TitriLyzer™ Series, two distinct titrimetric techniques are available in function of the measuring range, the application and parameter.

  • Acid-base, redox or precipitation titration are typically used in the potentiometric configuration, where the endpoint is determined by use of a pair of electrodes or a combination electrode, i.e. the indicator and reference electrode.
  • In the (photo)colorimetric analyzer configuration, color change is used to determine the endpoint of the titration.

Application fields

On-line monitoring of chemical parameters and quality indices in both clean and dirty water types:

  • Boiler feed water / steam cycle monitoring
  • Anaerobic digestion control
  • Drinking water monitoring
  • Waste water monitoring


The TitriLyzer™ is also known as the Hach EZ4000/5000 Series and available worldwide through your local Hach team.
