BL-7916-2 pH Controller and Pump information

Hanna's extended description

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.




Order Information:

The BL 7916 series is supplied with discharge and suction valves, polyethylene tubing, power cable and instructions.



Mains powered - All mains operated equipment is compatible with UK AC voltage and frequency – 230V, 50Hz.



Interchangeable Electrode - One controller for all jobs thanks to HANNA’s wide range of interchangeable electrodes. Simply change the electrode for the task ahead.
