Detailed Description
Specifications
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.
