A probe for determining moisture content of a medium includes a heating element and a temperature sensing element which is spaced from the heating element. The heating element within a tube is energized for a period of time, and the temperature change of the sensing element after that time is a function of moisture content within a range of tolerance which is acceptable for agricultural and most other purposes. Temperature readout means are coupled to the probe to identify the temperature at that time and identify moisture content of the medium as a function of temperature.
