Accurate and Reliable
Simple and Easy Installation
Perfect for use in CO2 Setups and Calcium Reactors
ACCURATE. SIMPLE. RELIABLE. 24/7 PH CONTROL.
The Milwaukee MC122 PRO pH controller lets you measure and adjust pH levels automatically.
WHAT PEOPLE ARE SAYING
"I run this unit 24/7 and have not had any problems for the past two months. It keeps my fish tank CO2 injector running perfectly and puts my mind at ease regarding overdosing."
"I've been using this controller for two years to monitor and adjust pH of hydroponic nutrient solutions. Still using the original probe and it rarely needs calibration."
"Using this as a pH controller for a calcium reactor on a 105 gallon reef tank ... I recommend this to any serious reefer."

USE AND CARE
pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.
SENSING BULB
The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.
REFERENCE JUNCTION
The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function.
You can extend the life of your pH electrode in the following ways.
STORAGE
The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.
Storing in a pH probe storage solution or pH calibration buffers will help address both these issues. Do not store it in tap water and DI water. This will damage the sensitivity of the probe.
The best way to store the probe is with the probe's cap filled with a storage solution for calibration buffer and the cap tightened to prevent leakage. It is also recommended to store the electrode upright to further reduce the potential for leakage.
CLEANING
Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in a cleaning solution.
CALIBRATION
The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.
