Full Description Specification Manuals
  • ORP controller and dosing pumps in one compact unit.
  • ±5 mV accuracy with unbeatable performance.
  • Isolated 4 to 20 mA recorder output.
  • Proportional dosing slows the pump down when the measured ORP level approaches the set value which avoids over dosage of oxidising or reducing agents.
  • Alarm contact is activated whenever the ORP reading varies more than 200 mV 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.
