Milwaukee MA911B/2 Lab Grade Double Junction pH Electrode with Extended Cable
Pickup currently unavailable at Banarsi Canal Linking Road, Near Shadani Darbar, Banarsi, Mana, Raipur (C.G.) - 492015
Description
The MA911B/2 probe is lab grade, gel-filled pH probe for use with Milwaukee Monitors and Controllers.
DESIGN FEATURES
Top features include:
DOUBLE JUNCTION
The double junction junction design reduces the risk of clogging.
SPHERICAL GLASS TIP
The spherical glass tip provide the largest possible surface area for faster results.
RESIN BODY
The resin body is tough to withstand accidental knocks and also protects the glass sensing bulb.
EXTENDED CABLE
Offers a 6.6 feet cable for increased flexibility in measuring.
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 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 that 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 block the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in 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 meter accurate. Also, calibrate after cleaning or a long period of storage.

Needed new probes for my apex unit. These were cheaper and are just as accurate. Great economical replacement
Calibration holds well⦠seems sturdy and exactly like the originL
I had to replace an Atlas Scientific Consumer Grade pH probe that had readings drifting (even after multiple re-calibrations) after less than 1 year.... scanned Amazon and this item popped up. Based on other reviews I went for it. Looks relatively rugged ( for this type of instrument and cost. ) Reading "snapped" in SURPRISINGLY fast and stabilized very quickly (compared to other "cheap" probes I have) even on big pH swings. I have it connect to an Atlas Scientific EZO⢠pH Circuit on an Electrically Isolated EZO⢠Carrier Board via BNC->SMA adapter. I did a 3 point calibration and I'm back in action! Depending on how it performs over time I'm planning on picking up a spare for the shelf at this point. Will update if there are any major issues or setbacks.
excelente productos llevo tiempo usandolo y me parece muy bueno
PH probe came without any storage solution. it looks like it leaked out. Looks like im out of my money. been using these for 5 years and this is the first bad one. wish they would replace it.
