Fermometer

Liquid crystal thermometer which adheres to the side of a carboy, bucket, or even stainless conical to tell you the fermentation temperature. 36-78 F range. 

Handy suggested Lager and Ale temperature ranges printed right on it. An example of the more precise scale would be that on this unit it easy to tell 1 degree of difference, say between 72 and 73 degrees.

    Very handy and easy to read.
