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.
