Simplified Accuracy for Everyday Brewing

The Milwaukee pH54 is a rugged, waterproof pH tester designed for homebrewers who want consistent, accurate results without breaking the bank. With a resolution of 0.01 pH and accuracy to ±0.1 pH, this compact tool is a reliable upgrade from test strips or basic meters. It’s ideal for checking mash and sparge pH, monitoring your water adjustments, or tracking fermentation progress with digital precision.

The pH54 features a replaceable double-junction probe for long-lasting performance, a wide pH range from 0.00 to 14.00, and a large, easy-to-read LCD. It uses manual 1- or 2-point calibration and is fully waterproof to IP65 standards. If you're looking for a straightforward, affordable digital pH meter that’s built to last, the pH54 has you covered.
