A Product by WTW GmbH
OverviewSpecificationsResources
The Multi 3320 for measurement of pH, ORP, conductivity, and dissolved oxygen (electro chemical) is a perfect meter for environmental applications in ground and surface water measurement, aquaculture, waste water treatment plants and much more.
  • Enhanced measurement functionality
  • pH, ORP, ISE, Conductivity, Dissolved Oxygen
  • For all conventional single parameter sensors
  • Two inputs for simultaneous measurement of pH and conductivity, or pH and dissolved oxygen.
  • Backlit LCD for displaying two measurements at the same time
  • For all conventional WTW pH, combined ISE, conductivity cells and electrochemical D.O. sensors
