Detailed Description
Specifications
Description • 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.
