HANNA BL 7916 pH Controller + Dosing Pump, BL7916

pH Controller and Pump

* Proportional dosing * ±0.01 pH accuracy with unbeatable performance * Isolated 4 to 20 mA recorder output

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 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. PVDF, FPM/FKM and PTFE materials are used for all parts that come into contact with liquid.
