One of my FLUKE meters has a thermistor wire thingy which plugs into the
meter.I am going to use it and check the freezer compartment temperature
and also the non freezer part of my old Dometic (Dometic, brand name) RV
refrigerator.I know it gets cold inside there.Sometimes I turn it off
for a while untill the ice inside of the freezer compartment melts so I
can wipe it up.
