What do you use for a refrigerator Thermometer ?

I use one that shows four temps. Have one probe in the freezer, one in the refer, and one with a probe on about a 30" cord that hangs just the below the front end of the MH for the outdoor temp. The screen also shows the temp inside of the MH.

If you buy one, buy an extra sending unit or two because you may not find them in a couple of years when one quits working. That will save you from starting all over buying a totally new set up.
