Simple stickon temperature monitoring: press the adhesivebacked thermometer onto the outside of your fermenter for an immediate, accurate surface reading of fermentation temperature. Clear LCD readout: easytoread display shows current temperature at a glance so you can make timely adjustments to fermentation conditions. Builtin yeast guidance: the display includes the ideal brewing range for various yeasts used in homebrewing, helping you keep ale and lager fermentations inside recommended temperatures. Secure adhesion for consistent readings: strong adhesive backing keeps the unit in place for repeatable, precise measurements throughout the fermentation cycle. Why you need it: consistent fermentation temperature is critical to yeast performance and beer flavor. This stickon thermometer removes guesswork and helps prevent offflavors caused by too or toolow temperatures. How it solves common problems: eliminates the need to open your fermenter or disturb the brew to check temperature, reducing contamination risk and heat loss while giving continuous temperature visibility. Use scenarios During primary fermentation: attach the thermometer when you pitch yeast and monitor temperature throughout the active phase to ensure yeast stays within its recommended range. Temperaturesensitive recipes: use the LCD guidance when brewing ales or lagers that require narrow temperature control to achieve the desired flavor profile. Conditioning and resting: keep the thermometer in place during diacetyl rests or cold conditioning to confirm you've reached and maintained target temperatures. Key functions and compatibility Function: surface thermometer with adhesive backing and LCD display for direct temperature monitoring of homebrew fermenters. Compatibility: designed for use on homebrewing fermenters (buckets, carboys, and other sealed vessels) to provide a noninvasive temperature reading. Performance: provides continuous, easytoread temperature feedback and highlights ideal ranges for common brewing yeasts to support consistent fermentation results.
