Dosing Pumps w/pH Controller
  > Printable version
  • pH controller and dosing pump in one compact unit.
  • ±0.01 pH accuracy with unbeatable performance.
  • Isolated 4 to 20 mA recorder output.
  • Proportional dosing slows the pump down when the measured pH level approaches the set value which ensures precise dosage and avoids costly waste of chemicals due to overdosage.
  • Alarm contact is activated whenever the pH value varies by more than 2 pH units from the setpoint.
  • Auxiliary Contacts allow the user to attach a mixer or priming pump that is activated only when the pump is dosing.
  • Kynar® and Teflon® materials are used for all parts that come into contact with liquid.
