BrewMometer™ with 1/2″ NPT is perfect for a brew pot with a 1/2″ female NPT coupling already installed. Reads 60°F to 220°F. Stainless steel thermometer has a 3” dial face with critical brewing temperatures marked. Includes a calibration screw. Stem only protrudes about 2″ into the pot – deep enough for an accurate reading, shallow enough to stay out of the way of your stirring paddle.
