The Mad Brewer™ Deluxe Brew Lab Kit gives you the essential tools to take full control of your brewing process—from mash pH to fermentation temperature and gravity readings.

The Brix/Specific Gravity Refractometer lets you monitor gravity without pulling a full test jar sample—perfect for quick checks during mash, boil, or fermentation.

The heart of this kit is the Milwaukee pH55 pH/Temperature Meter, a durable, waterproof pH meter with automatic temperature compensation and a digital temperature display. It helps you dial in mash pH for enzyme activity, yeast health, and consistent flavor.

To round out your brew day toolkit, we’ve included the Northern Brewer Folding Digital Thermometer for accurate temp readings, and the Digital Pocket Scale for precision hop or salt additions. Plus, you’ll get a 1 lb supply each of gypsum and calcium chloride to start building your perfect brewing water profile.
