DetailsKeep your fermentation on track with the FermagraF°™: purposefully designed to adhere to your Big Mouth Bubbler® fermentor or other fermentation vessel. This thermometer uses liquid crystals to indicate temperature within ±2°F ranging from 46°F to 84°F. The new circular design is meant to keep the information you need in one compact space so that you can quickly read your fermentation temperature at a glance.
In addition, the FermagraF°™ has clearly marked fermentation temperature ranges for Lagers, Ales, and Belgian Ales, and your Red and White wines so that you can always ensure that your yeast is kept nice and comfy.
Dimensions: 3" x 3"

over 2 years agoLaid out really well and easy to read. Only complaint is that the temps are kind of hard to see unless you shine a light on it. Would be nice if the numbers were a little brighterMay 2, 2018Purchased

1 year agoLike a gloveIs how it fits on a Big Mouth Bubbler. Seems fairly accurate in that with an external reading of 52ish, I got an actual of 50.5 from thermometer directly in sample.March 13, 2018Purchased
1 year agoI don’t like this thermometer, but it helps.First, it worked good, I can see my beer between 70 F and 68 F for 2 weeks, but now that I needed it cooler, some days I can’t read this thermometer, I can’t see the correcto grade because it’s so lightly... but TODAY is a great day because I can read it... I can see it in 50 F.... so, It’s not the best thermometer but having nothing would be worst.February 27, 2018Excellent device.This device makes it easier to roughly check the temperature on my carboys on a daily basis. I still use a glass thermometer when taking gravity readings.March 8, 2017Purchased

Browse 2 questions Browse 2 questions and 15 answersIs this thermometer for one use only?BEST ANSWER: You apply this to the outside of your carboy (glass or plastic) and you're good to go. It has adhesive on the back but is not meant to be pulled off and moved to another vessel. Do not store your carboys where they are exposed to extreme heat and they should last for years. Cheers.Is there one place better than another to place it on the Bubbler?BEST ANSWER: I feel it is best to have the guage near the middle of the carboy where most of the wine is.
