pH Controller and Pump


Features:

  • pH controller and dosing pumps 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 valve which ensures precise dosage and avoids costly waste of chemicals due to over dosage
  • Alarm contact is activated whenever the pH value varies more than 2 pH units from the set point
  • Auxiliary contacts allow the user to attach a mixer or priming pump that is activated only when the pump is dosing
  • High Quality materials are used for all parts that come into contact with liquid
