Hanna BL-7917-2 ORP Controller and Pump

  • 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
