The Zetasizer WT is a fully automated system that delivers lab quality on-line zeta potential measurements. This enables real-time monitoring of flocculation process performance and efficient charge neutralization. On-line charge measurements you can trust are finally here!

The Zetasizer WT combines Malvern Panalytical’s industry leading Electrophoretic Light Scattering technology with two decades of expertise with in-process measurements to produce a dedicated on-line zeta potential analyzer for water treatment plants.

The Zetasizer WT connects to a sample stream coming from the plant after coagulants have been added and mixed into the water. The system uses a pump to flow a sample through the analyzer`s flow cell where zeta potential measurements are made.

No more guess work – accurate and reliable results in [mV] provide a clear range for dosing control.

Respond to changes in raw water before they cause filtration problems!

Reduce chemical use to optimum for forming a stable floc. Overdose no more!



  • Completely automated zeta potential analysis with results in minutes.
  • Results sent to SCADA via OPC, Modbus or 4-20mA.
  • Minimal maintenance.
  • Easy measurement of grab samples on the same system.
  • HMI for local control and setup.
  • On board computer for autonomous operation.
  • Sample flow and temperature sensing.
