Some of us have been known to lose track of time when immersed in our 'hobby'. This large 10" diameter wall clock, thermometer, & hygrometer makes a nice addition to any brewing room and may even help to keep you out of trouble. The clock has easy to read numbers (i.e. you can still read it after having a couple to drink)with the thermometer and hygrometer built into the middle. The hygrometer measures humidity levels. Makes a great gift for any brewer.
