Features

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, to avoid overdosage 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 users to attach a mixer or priming pump that is activated only when the pump is dosing
PVDF, FPM/FKM, and PTFE materials are used for all parts that come into contact with liquid.

The controller/pump is enclosed in modular housing for maximum protection. The pump utilizes a one-piece polypropylene, injection-molded housing. Since there are no joints or screws holding different sections of the housing together, the case is extremely rugged and sturdy. This series of instruments will mount easily in your plant using a minimum of wall space. The controls and pump head are located in the front to allow easy access.
