Emaux Control Plus 4 Automatic PH Dosing & Measurement System



For Automatic measurement of the PH value and Dosing of PH Reducing Fluids.

With its compact structure, sleek design, intelligent micro controller, professional recognition and easy to install and operate our Control Plus Digital metering pump with pH/Redox control meter on board features an adjustable manual control with proportional dosing flow rate for the right pH & Redox management.

The automatic monitoring system measures the PH value and Redox / ORP value of water through the relative voltage of probes with total control & dosing through the desired set-point.

The microcontroller based dosing pump which includes both a dosing pump and high tech controller which features two parameters all in one enclosure: PH or RX (ORP)

The dosing pump is activated by a PTFE diaphragm mounted onto a piston operated by pulses received from the electromagnet. Return phase is spring operated. Control circuit is SMD (surface mounting device) with microcontroller technology, digital controls, display and LED indicators for visualizing pump status.

The operations are simple, pump doesn’t need lubrication, and therefore maintenance is reduced almost to zero.

The Emaux Control Plus 4 has an injection rate of 4 Litres per Hour
