The Liquitron™ DR5000 Series ORP (Oxidation Reduction Potential) Controllers are designed for a variety of industrial ORP applications including metal finishing, water treatment, printed circuit board manufacturing and waste treatment. The DR5000 is a microprocessor-based ORP controller with a backlit customized display and tactile keypad for ease of programming. The DR5000 allows independent programming of control methods (On/Off or Proportional) for reducing agent (Pump A) or oxidizing agent (Pump B) dosage. Independent high and low ORP alarms may be set with activation of the ‘Alarm relays.’ A third relay output is available for activating a solenoid valve or other devices.
