FermagraF°® Adhesive LCD Thermometer
- Bright blue color is easy to read at a glance.
Keep your fermentation on track with the FermagraF°® -- designed to adhere to your Big Mouth Bubbler® fermentor or another 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.
Dimensions: 3" x 3"
Works like a charm! Make sure to apply in middle of carboy. I attached my first one near the top curved glass area and it got all wonky.
These are okay but not real impressed. I prefer the Therometer. I couldn't find them on NB but Walmart .com has them for $6.
Hard to read the LCD display
For me, I always have to use a flashlight to see which one is showing. It’s a really convenient way to have it mounted to the side of the fermentor, just wish the numbers were brighter.
I have these on most of my small batch 1 gallon fermenters. It's a convenient way to check to make sure those temps are where ya want 'em.
