MA9015 is a lab grade electrode storage solution prepared with premium chemicals to improve the performance and extend the life of your pH and ORP electrodes, testers and pens.
To ensure a quick response and free-flowing liquid junction, the sensing element and reference junction must not be allowed to dry out. Properly storing your pH electrode in a solution keeps the glass membrane well hydrated which maintains proper function and provides accurate readings.
MA9015 also helps keep the junction in your pH and ORP electrode flowing which is critical for fast results.
DESIGN FEATURES
Fundamental for the correct use of electrodes and for obtaining the most accurate and reproducible readings.
Formulated to minimize organic growth on your electrode.
Sealed against light with air tight, tamper proof cap.
Factory blended to precise standards in a dedicated, temperature controlled environment.
Simply open and add to the cap of your electrode or tester.
Each bottle marked with lot number and expiration date.
MA9016 is a lab grade electrode cleaning solution prepared with premium chemicals to improve the performance and extend the life of your pH and ORP electrodes, testers and pens.
Your accuracy and speed of your results are dependent on your pH sensing bulb and ORP platinum tip being clean. pH and ORP electrodes also need a free flowing junction to function.
Milwaukee's cleaning solution helps both keep sensing parts clean and the junction open. Simply open the bottle, fill a beaker or container so that the level covers the sensor and junction, and soak for 15 to 20 minutes followed by a soaking in MA9015 storage solution for at least 2 hours.

USE AND CARE
“OPEN AIR” CALIBRATION PROCEDURE FOR THE MW600 DISSOLVED OXYGEN METER
1. Remove the membrane
Take the membrane off the end of the probe and dry the diode off.
2. Zero out the display
Connect the probe to the base unit and turn the unit on. Your display should read 0.0. If it does not, go to the position “0” screw on the front of the unit with the screw driver provided and through the access hole make the unit display read 0.0.
3. Fill the membrane
Go to the membrane and put the “O” ring inside the membrane on the shoulder at the base of the threads. Fill the membrane to just short of the “O” ring with MA9071 electrolyte solution. Be sure that there are no bubbles inside the membrane. (Air bubbles are the main cause of calibration failure)
4. Attach the membrane
Screw the membrane on to the probe.
5. Let stabilize
Turn the meter on and hang the probe off the end of a table pointing down and let the unit display stabilize (this may take 5 to 15 minutes)
6. Adjust
Push down and hold the “Cal” button on the front face of the meter and with the screwdriver go to the front Cal position “100%” and make the display read 100.
You are now calibrated.
EXTRA TIPS
Watch for the membrane having wrinkles or stretch marks. If you see wrinkles, replace with a new membrane.
Always use fresh electrolyte solution (MA9071).

3 feet probe cables for extra flexibility when testing.
Auto shut off and low power demand for approx. 300 hours of continuous use. (battery included)
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.
CLEANING AND STORAGE
All pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH pen tester will give you fast, accurate results for longer. So, be sure to order the Milwaukee codes MA9015 and MA9016 at checkout time! This will be needed to help clean and condition the pH electrode before use!
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 MA9015 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 clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution MA9016.
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.
