Milwaukee MA911B/2 Lab Grade Double Junction pH Electrode

 

Milwaukee MA911B/2 Lab Grade Double Junction pH Electrode with Extended Cable

The MA911B/2 is a lab grade, gel filled pH probe for use with Milwaukee Monitors and Controllers. 

The resin body is tough enough to withstand accidental knocks while also providing protection for the glass sensing bulb.  The double junction design reduces the risk of clogging and the spherical glass tip provides the largest possible surface area for faster results.  The probe comes with a 6.6-foot cable for increased flexibility in measuring. 

Specifications:

  • Body: Resin
  • Reference: Single, Ag/AgCl
  • Junction: Ceramic, single
  • Electrolyte: Gel
  • Range: 0-14 pH
  • Tip Shape: Sphere
  • Diameter: 0.5 inches
  • Dimensions: 4.7 inches / 6.4 inches
  • Operating Temperature: -5 to 70°C (23 to 158°F)
  • Cable length: 6.6 feet
  • Connection: BNC

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.
