Best Answer

It is a simple device. A variable electronic resister, called a thermistor, is used and is on the end of the cord. The resister varies it's resistance value depending on temperature. The probe must be placed in the area (outside) where you want the temperature. There is a second one in the unit itself and will show the inside temperature.
