Milwaukee MC122 PRO pH Controller

Milwaukee MC122 PRO pH Controller

The MC122 controller automatically monitors and fine-tunes pH levels. Simply set pH parameters and the Milwaukee pH Controller will do the rest.  It 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 and aquariums.

The meter has a 2-point manual calibration and is accurate to ± 0.2 pH.  The controller provides a control range of 5.5 to 9.5 pH with alarms that activate when readings are higher or lower than set point. 

The pH Controller comes with a complete mounting kit including a probe holder. 

Features:

  • Fast, easy-to-read current results with large digital LCD readout
  • Accurate to ±0.2 pH (0.0 pH to 14.0 pH) with user selectable high/low set points
  • Simple two-point calibration for increased accuracy and manual trimmers for easy adjustment
  • Gel-filled, double junction lab grade pH electrode for low maintenance and high performance
  • 5-foot probe cables for extra flexibility when testing
  • 12 VDC power supply

Milwaukee MC122 Manual

CARE AND USE

pH meters usually start performing poorly because of problems with the probe, specifically the glass sensing bulb and the reference junction.  The glass bulb loses sensitivity with use and will eventually fail, which is true of all pH probes.  The reference junction is a small hole that allows the meter to compare the sample to a reference.  If the junction hole gets clogged, the pH probe will no longer function.

The life of your pH electrode can be extended in the following ways:

  1. 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 pH probe storage solution or pH calibration buffers will help address both these issues. Do not store 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 storage solution or 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.
  2. 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. It is recommended to regularly soak your electrode in cleaning solution.
  3. Calibration - The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.
