Continuous pH Monitoring for Acidic Applications
The Milwaukee MC110 PRO pH Monitor provides 24/7 pH monitoring optimized for mid-range acidic applications. With a customizable alarm setpoint from 3.5 to 7.5 pH, the MC110 PRO is specifically designed for brewing, winemaking, hydroponics, and other applications where pH typically stays in the acidic to neutral range.
Why Mid-Range Monitoring?
Many critical applications operate in the 3.5-7.5 pH range: beer mash (5.2-5.6), wine (3.0-4.0), hydroponic nutrient solutions (5.5-6.5), and food production processes. The MC110 PRO's focused setpoint range allows precise alarm configuration for these applications without the broader range needed for pools or alkaline processes.
Key Features & Benefits
Continuous pH Monitoring
The large digital LCD display provides an always-visible pH reading across the full 0.0-14.0 pH range. Monitor pH trends continuously and catch problems before they impact your process, product quality, or crop health.
Mid-Range Alarm System
Set your ideal pH alarm anywhere between 3.5 and 7.5 pH. The visual alarm activates when pH readings move higher or lower than your setpoint, alerting you to take corrective action immediately. This focused range is perfect for:
-
Brewing: Set alarms for mash pH (5.2-5.6) or fermentation monitoring
-
Winemaking: Monitor must and wine pH (3.0-4.0) during fermentation and aging
-
Hydroponics: Maintain optimal nutrient solution pH (5.5-6.5) for maximum uptake
-
Food Production: Monitor acidic processes, fermentation, and product pH
Lab-Grade Accuracy
With ±0.2 pH accuracy across the full 0.0-14.0 pH range and 0.1 pH resolution, the MC110 PRO delivers reliable data for professional applications. Two-point manual calibration ensures accuracy over time.
Professional MA911B/2 Electrode
Includes the Milwaukee MA911B/2 double junction, gel-filled pH electrode designed for continuous immersion and low maintenance. The double junction design prevents sample contamination and extends electrode life, especially in organic-rich samples like wort, wine, and nutrient solutions.

Professional Applications
Brewing: Mash pH Monitoring
Mash pH is critical for enzyme activity and extraction efficiency. The optimal range of 5.2-5.6 pH is narrow enough that continuous monitoring with alarms provides real value. Set the MC110 PRO's alarm for 5.2 and 5.6 pH, and you'll be notified immediately if mash pH drifts outside the optimal range.
The MA911B/2 electrode handles the sugars and proteins in wort without fouling, while continuous monitoring eliminates the need for constant manual testing during the mash. Mount the monitor in your brew house for at-a-glance pH visibility throughout the brew day.
Winemaking: Fermentation & Aging
Wine pH typically ranges from 3.0 to 4.0, well within the MC110 PRO's mid-range alarm capability. Monitor must pH during fermentation, track pH changes during malolactic fermentation, and verify pH stability during aging.
The double junction electrode resists the organic acids and alcohol in wine that quickly compromise standard pH probes. Continuous monitoring helps winemakers make informed decisions about acid additions, SO₂ management, and fermentation timing.
Hydroponics: Nutrient Solution Management
Most hydroponic crops thrive in the 5.5-6.5 pH range where all essential nutrients remain available. The MC110 PRO continuously monitors nutrient solution pH and alerts you to drift immediately, preventing nutrient lockout that reduces yields.
Set alarms for your crop's optimal pH range, and respond quickly when pH moves outside acceptable limits. The continuous monitoring eliminates the guesswork of periodic manual testing and catches pH problems before they impact plant health.
Food Production & Fermentation
Many food production processes operate in the acidic range: yogurt production, cheese making, pickling, fermentation, and acidified foods. The MC110 PRO provides continuous pH oversight with alarm protection, ensuring processes stay within specification for quality and safety.
Electrode Care & Maintenance
The MA911B/2 electrode requires proper care to maintain accuracy and extend service life:
Storage
Keep the pH probe hydrated by storing in pH storage solution or calibration buffer. Never store in tap water or DI water, which will damage probe sensitivity. Store the electrode upright with the cap filled with storage solution to prevent leakage and maintain performance.
Cleaning
Regularly soak the electrode in pH cleaning solution to remove residue from organic-rich samples like wort, wine, or nutrient solutions. Clean the probe after use in challenging samples and before calibration to maintain sensitivity.
Calibration
Calibrate regularly using pH 4.01 and 7.01 buffer solutions (7.01 included as starter solution). The glass sensing bulb becomes less sensitive over time, so regular calibration maintains accuracy. Always calibrate after cleaning or extended storage periods.
