Hanna pH Controller and Pump; range: 0.00 to 14.00pH
Item Description: Hanna Instruments BL 7916 0 to 14.00 pH Controller and Chemical Dosing 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, to avoid over dosage of oxidizing or reducing agents
- Alarm contact is activated whenever the ORP reading varies more than 200 mV from the set point
- Auxiliary contacts allow users 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
