The Milwaukee MW150 MAX pH Bench Meter offers:
People choose the MW150 MAX 3-in-1 pH/ORP/Temp Meter to improve the accuracy of their testing program. With up to 3 point calibration and 7 standard buffer choices, the meter can be quickly calibrated to a higher accuracy compared with 1 or 2 point calibration. The MW150 MAX Bench Meter is accurate to0.01 pH. 5x more accurate than some alternative meters.
The meter comes with a double junction pH electrode (included) and temperature sensor MA831R (included) allowing the meter to automatically adjust the pH reading for the effect of temperature (ATC).
The meter can also be used as a very accurate thermometer with accuracy /-0.4°C | /-0.8°F.
The rugged meter is built to take knocks and is sleek and lightweight .
The MW150 MAX pH/OPR/Temp Bench Meter comes with the Milwaukee refillable glass MA917B/1 pH electrode and has a BNC connector allowing easy interchange to any pH Milwaukee electrode. This is Milwaukee’s top selling lab grade electrode for a reason. Designed to be both low maintenance (refillable) and able to withstand more challenging samples (double junction). The MA917B/1 is ideal for use in beer making, winemaking and hydroponics, environmental labs and many other applications.

- 3 feet probe cables for extra flexibility when testing.
CARE AND USE
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.
The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.
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 electrode will no longer function.
You can extend the life of your pH electrode in the following ways.
To minimize clogging 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 or 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 AN MAINTENANCE
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. Also:
1. Inspect the electotrode for damage or scratches, if present replace the electrode.
2. Inspect the cable. The connection cable and insulation must be intact.
3. Connectors should be clean and dry.
4. Rinse off salt deposits with water or DI water.
The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO Plus Bench pH Meter accurate. Also, calibrate after cleaning or a long period of storage.
