Description

The Milwaukee MC125 PRO pH and ORP controller is designed for people looking to measure and adjust pH and ORP levels automatically with one simple controller. Just set your pH and ORP  parameters and let the Milwaukee pH Controller do the rest.

The Milwaukee PRO pH / ORP controller is preferred by people looking to dial in their testing program when they have an ongoing need to maintain levels. Common uses are nutrient tanks, aquariums, pools, and spas. 

The Milwaukee PRO pH / ORP controller offers:

  • Accuracy

The Milwaukee PRO 2 in 1 controller offers an accuracy to ±0.2 pH with two point manual calibration and ORP accuracy to ±5 mV.

  • Real-time monitoring

See real-time pH and ORP measurements from 0.00 pH to 14.00 pH and -1000 mV to 1000 mV with a large LED with easy switching between parameters.

  • Automation for constant measurement

The controller provides a control range of 4 to 8 pH and -200 to 600 mV. Just set your control range and the controller do the rest.

  • Two dedicated relays for pH and ORP control to support a range of compatible devices

Choose your device including oxygen pumps, CO2-regulators, O3 ozonizers and other pH & ORP control devices by simply plugging the device into the correct pH or ORP outlet. 

  • Easy installation

The controller comes with a complete mounting kit including two probe holders.

Design features

  • Fast easy to read current results with large digital LED readout.
  • Accurate to ±0.2 pH and ±5 mV with the user selectable high/low set points.
  • Simple two-point calibration for increased pH accuracy with manual trimmers for easy adjustment.
  • Lab grade, gel-filled, double junction pH electrode and platinum ORP electrode included for low maintenance and high performance.
  • 6.5 feet probe cables for extra flexibility when testing.
  • 12 VDC power supply.

What People Are Saying

"I run this unit 24/7 and have not had any problems. It keeps my fish tank CO2 injector running perfectly and puts my mind at ease regarding overdosing."

Care and Use 

Properly maintaining your pH and ORP probes will give you fast, accurate results for longer. pH and ORP probes are similar in design but there are some differences.

pH probes have a sensing bulb that loses sensitivity with age. All pH sensors have a limited life and response time gets longer with age.

ORP probe have usually a platinum electrode instead of a glass bulb. This electrode has a longer life but can have a residue build up that affect response rates and accuracy.

Both electrodes have a reference junction that can become clogged resulting in slow and inaccurate results. Cleaning and keeping the probe hydrated will help prevent this.

  • pH Probe

Here are our top four tips for your pH probe.

1. Always store with the cap full of buffer or storage solution not water.

2. Clean your Probe regularly by soaking in cleaning solution.

3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.

4. Gently stir the Probe in the sample for a faster result.

  • ORP Probe

Here are our top three tips for your ORP probe. 

1. Always store with the cap full of buffer or storage solution not water.

2. Clean your probe regularly by soaking in cleaning solution.

3. Calibrate after cleaning and/or storage before testing to adjust for changes in the ORP probe sensor.
