Blichmann Engineering BrewMometer Weldless Adjustable ºF Thermometer
Adjustable-face thermometers are ideal for homebrewing. Because the face can be moved to any position, they're great for multi-tier stands. With Blichmann Engineering's patented BrewMometer™, you'll no longer have to stoop over or use a stool to read the temperature. Once you use the adjustable BrewMometer™, which is the best weldless design available, you'll never go back!
