WaterInspector measures, analyses and adjusts chlorine, chlorine dioxide or ozone. Being a generalist system, Water Inspector is one of the leading systems in the market. It is in particular characterized by its high operating reliability, long sensor lifetime of disinfection probes and high availability. The measuring system is self-monitoring and pressure-resistant up to 10 bar. Perfectly suitable for use in hospitals, hotels, sports facilities, industrial plants, etc. – everywhere where an effective and reliable disinfection is required.

Description

  • Complete measurement and control system
  • Potentiostatic measurement principle
  • Plausibility check of the measured values by evaluating the redox potential
  • Automatic temperature compensation of the measured values
  • Pressure-resistant up to 10 bar at 20°C
  • Sample water temperature 0 – 70°C
  • Integrated flow monitoring and limitation
  • Backlit graphic display
  • Clear menu control in plain text

 

The complete measurement and analysis system is mounted on a base plate
h/w 550/600 mm, ready for connection.
The entire system is covered with an easily removable cover.
The user interface is accessible at all times through an opening in the cover.
