For the serious brewers out there, beer nerds, and techies alike, this is the thermometer you want!

  • Know EXACTLY what your temperature is when you are brewing with the Calibrated Thermometer or a thermometer that you have checked with this thermometer.
  • You will receive a Calibration Certificate when you purchase this Thermometer.

  • Perfect for calibrating temperature probes in brewing systems like HERMS or RIMS
  • Proprietary "Precision Blue" internal liquid gives accuracy as close as possible to mercury and is ASTM approved.
  • Not all lab thermometers are made the same, these thermometers are much more accurate than the "classroom" grade often sold to homebrewers.

  • During our in house testing using the calibrated version of this thermometer we have seen other brands be as much as 5° off actual temperature which can cause issues when brewing
