The Milwaukee MW102 PRO+ pH meter has won fans around the world with its reliable, fast and simple operation as well as its toughness. Accurate to 0.02 pH with automatic temperature compensation. Ideal for use by brewers, wine makers, growers and other users with challenging pH measurement needs.
"Amazingly accurate, the best meter I have used so far."
"Very satisfied, very accurate, rugged device that calibrates easily."
"Rarely needs to be calibrated and gives perfect readings every time."
"Killer tool, good value."
The digital Milwaukee PRO+ pH Meter is preferred by people testing samples that cause other pH testers and meters to fail from brewers and wine makers to hydroponic growers and farmers.
The Milwaukee PRO pH meter offers:
People choose the digital PRO+ pH Meter to improve the accuracy of their pH testing program. With two point calibration, the meter can be quickly calibrated to a higher accuracy compared with one point calibration. The MW102 meter is accuracy to 0.02 pH. 5x more accurate than some alternative meters.
The meter comes with both a pH probe and temperature probe allowing the meter to automatically adjust the pH reading for the effect of temperature.
The temperature probe can also be used as a very accurate thermometer.
The rugged, digital pH meter is built to take knocks.
The PRO+ pH meter comes with the Milwaukee SE220 pH probe. The SE220 is Milwaukee's top selling lab grade electrode for a reason. Designed to be both low maintenance (gel filled) and able to withstand more challenging samples (double junction). The SE220 is ideal for use in beer making, winemaking and hydroponics.
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.
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 pH Maitenance Kit code PH-Main at checkout time! This will be needed to help clean and condition the pH electrode before use!
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.
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.
The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO Plus pH meter accurate. Also, calibrate after cleaning or a long period of storage.
The Milwaukee MW500 PRO ORP meter is one of Milwaukee's most popular meters with its reliable, fast and simple operation as well as its accuracy.
The Milwaukee PRO ORP Meter is preferred by people looking to dial in their testing program when they have an ongoing need to maintain levels. Common uses are aquariums, swimming pools and spas, and other water quality monitoring uses.
The PRO ORP meter can also be used to measure sulfur dioxide in wine using the manual Ripper titration method.
The Milwaukee PRO ORP meter offers:
The PRO ORP meter is accurate to ±5 mV exceeding the needs of most users.
The rugged meter is designed to take knocks.
The PRO ORP Meter comes with SE300 ORP probe that is both low maintenance (gel filled) and able to withstand more challenging samples (double junction).
Properly maintaining your ORP probe will give you fast, accurate results for longer.
Here are our top three tips.
1. Always store with the cap full of buffer or storage solution not water.
2. Clean your probe regularly by soaking in cleaning solution.
3. Check the probe using MA9020 200 - 275 mV solution to ensure the probe is good.
