The Liquitron™ DP5000 Series pH Controllers are designed for a variety of industrial pH applications including metal finishing, water treatment, printed circuit board manufacturing and waste treatment. The DP5000 is a microprocessor-based pH controller with a backlit customized display and tactile keypad for ease of programming. The DP5000 allows independent programming of control methods (‘ON/OFF’ or ‘PROPORTIONAL’) for acid (Pump A) or base (Pump B) dosage. Independent high and low pH alarms may be set with activation of the ‘Alarm relays.’ A third relay output is available for activating a solenoid valve or other devices.
