HANNA BL 7917 ORP Controller + Dosing Pump

HANNA BL 7917 ORP Controller + Dosing Pump, BL7917

• 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 oxidizing 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.
