Advanced Accuracy for Confident Brewing
The Milwaukee pH56 PRO is our most accurate handheld pH meter—designed for brewers who want precise data they can trust. With a pH accuracy of ±0.05 and 0.01 pH resolution, this tester provides highly sensitive readings across a broad range, from -2.00 to 16.00. Its automatic temperature compensation and dual-level LCD make it easy to monitor mash and fermentation conditions in real time.
The pH56 PRO is waterproof (IP65-rated), lightweight, and built for brewing environments. It features a replaceable Mi56P double-junction electrode for long life and consistent performance, along with one- or two-point automatic calibration. Whether you're fine-tuning your water chemistry, tracking pH changes during fermentation, or dialing in that perfect sour, the pH56 PRO is the tool of choice for serious homebrewers.
