The Thrumometer from Blichmann Engineering is a handy thermometer that uses a liquid crystal thermometer to deliver almost instantaneous, accurate feedback on temperatures of liquids that flow through it, meaning on-the-spot adjustment of flow rates to compensate for too hot or too cold wort, meaning that you can get your wort to the perfect temperature! With a smooth, easy-to-clean interior, there is nowhere for harmful bacteria to hide. Made of high-quality, corrosion resistant aluminum, there is never any need to calibrate the Thrumometer. The 1/2 in. barb fittings are perfect for the majority of most homebrew tubing. Made for lifetime use, there is no better inline thermometer!
