Take automated pH management to the next level with the Milwaukee MC720 PRO pH Controller & Dosing Pump Kit, a complete monitoring and dosing solution designed to measure pH continuously and automatically activate dosing equipment based on your selected set point.

The MC720 combines Milwaukee's MC122 PRO pH Controller with the MP810 peristaltic dosing pump, giving aquarists a straightforward way to automate applications where maintaining a target pH range is important.

Ideal for reef aquariums, calcium reactor systems, hydroponics, aquaculture and other water-quality applications, the MC720 provides continuous digital monitoring with automatic dosing control in one package.

Complete pH Monitoring & Dosing System

Rather than testing pH manually and making adjustments yourself, the MC720 continuously monitors the system using its included pH probe.

When the measured pH crosses the selected control point, the controller can activate the included dosing pump, allowing the system to automatically deliver the connected solution.

This makes the MC720 especially useful for applications requiring consistent, controlled pH management.

Included Peristaltic Dosing Pump
The included Milwaukee MP810 provides controlled liquid dosing without requiring a separate pump purchase.

Included pH Probe
The system includes the pH electrode required for monitoring and control.

Visual LED Alarm
A visual alarm provides additional indication when measurements move outside the selected control parameters.

Professional Monitoring Solution
Suitable for aquariums as well as aquaculture, hydroponic and other applications requiring automated pH control.

Milwaukee MC720 PRO product information

Excellent for Calcium Reactor Systems

The MC720 can be particularly useful for calcium reactor applications, where maintaining controlled pH within the reactor can help regulate media dissolution.

By combining continuous pH monitoring with automated dosing/control capability, the system provides reef keepers with another layer of automation for managing equipment where pH plays a critical role.

Always configure the controller and connected equipment according to the requirements of the specific aquarium system and application.

MC122 PRO pH Controller

At the heart of the MC720 is Milwaukee's MC122 PRO pH Controller.

The controller provides continuous pH measurement across a 0.0–14.0 pH measuring range, with an adjustable control set point from 5.5–9.5 pH.

Its digital display allows the aquarist to quickly check current pH while the controller handles the configured switching operation.

MP810 Peristaltic Dosing Pump

The included MP810 dosing pump allows liquid to be delivered automatically when activated by the controller.

Peristaltic pump operation keeps the liquid being dosed contained within the tubing, making it well suited to controlled aquarium dosing applications.

The combination of controller and dosing pump means you don't have to purchase and integrate two separate components to create a basic automated pH dosing system.

What's Included

The Milwaukee MC720 PRO kit combines the components needed to establish the monitoring and dosing system, including the MC122 PRO pH Controller, MP810 peristaltic dosing pump and pH electrode, along with the applicable manufacturer-supplied accessories.

Always refer to the included Milwaukee documentation for current package contents, setup, calibration and operating instructions.

Calibration & Maintenance

Like any precision pH instrument, proper calibration and probe maintenance are essential.

Calibrate the controller according to Milwaukee's instructions using appropriate calibration solutions, and keep the pH electrode properly maintained and stored when applicable.

The probe should never be allowed to dry out, and calibration should be checked regularly to maintain dependable control.

Important Dosing Notice

Automated dosing equipment should be configured carefully and monitored regularly.

Always verify the appropriate pH target for your application and confirm controller operation before relying on automated dosing. Aquarium conditions, probe calibration, tubing condition, dosing solution concentration and equipment configuration can all affect system performance.

For aquarium applications, changes to water chemistry should be made gradually and monitored with appropriate testing equipment.
