Milwaukee MW102 PRO+ pH & Temperature Meter + Hard Case Bundle
Get lab-grade pH accuracy with built-in automatic temperature compensation (ATC). This exclusive bundle pairs the Milwaukee MW102 PRO+ pH & Temperature Meter with the MI0028 hard plastic carrying case — a complete, field-ready kit for professional pH testing in breweries, wineries, hydroponic grows, labs, and food production environments.
Why the MW102 PRO+?
The MW102 PRO+ is the step up from the MW101 — it adds a dedicated stainless steel temperature probe and automatic temperature compensation (ATC), so your pH readings are always corrected for sample temperature without any manual calculation. Trusted by brewers, winemakers, hydroponic growers, and food scientists worldwide.

Probe Care & Maintenance Tips
Proper probe care extends the life of your MW102 PRO+ and keeps readings accurate:
-
Storage: Keep the probe hydrated in storage solution MA9015 or calibration buffer. Never store in tap water or DI water — this damages probe sensitivity and can clog the reference junction.
-
Cleaning: Soak the electrode regularly in cleaning solution MA9016 to remove residue, especially after testing organic samples like beer wort or must.
-
Calibration: Calibrate regularly, after cleaning, and after extended storage to maintain ±0.02 pH accuracy.
Pro tip: Add the Milwaukee pH Maintenance Kit (PH-Main) to your order to clean and condition the electrode before first use.
Frequently Asked Questions
- What is the difference between the MW101 and MW102 PRO+?
- The MW102 PRO+ adds automatic temperature compensation (ATC) via a dedicated stainless steel temperature probe (MA831R). This means pH readings are automatically corrected for sample temperature in real time, making it more accurate for samples that vary in temperature — such as fermenting beer, wort, or must. The MW101 requires manual temperature correction.
- What is the pH accuracy of the Milwaukee MW102 PRO+?
- The MW102 PRO+ has a pH accuracy of ±0.02 pH — lab-grade precision that is 5× more accurate than many basic pH meters. It covers an extended range of -2.00 to 16.00 pH.
- Does the MW102 PRO+ have automatic temperature compensation?
- Yes. The MW102 PRO+ includes a dedicated MA831R stainless steel temperature probe that provides automatic temperature compensation (ATC) from 0 to 70°C, ensuring accurate pH readings regardless of sample temperature.
- What electrode does the MW102 PRO+ use?
- It uses the SE220 double junction, gel-filled, lab-grade pH electrode. This electrode is low maintenance (no filling solution required), resistant to clogging, and ideal for challenging samples like beer, wine, and hydroponic nutrient solutions.
- Is the Milwaukee MW102 PRO+ good for brewing and winemaking?
- Yes. The MW102 PRO+ is a top choice for brewers and winemakers because of its ±0.02 pH accuracy, automatic temperature compensation (critical for fermenting samples), and the SE220 double junction electrode that handles organic-rich samples without clogging.
- How do you calibrate the MW102 PRO+?
- The MW102 PRO+ uses automatic 1- or 2-point calibration with pH 4, 7, and 10 buffer solutions. Two-point calibration is recommended for maximum accuracy. Calibrate before first use, after cleaning, and after extended storage.
- What does the MI0028 hard case include?
- The MI0028 is a hard plastic carrying case with a foam-cut insert that secures the meter and electrode during transport. It holds up to two PRO portable meters and features a carry handle and strong fasteners for long-term durability.
