ABSTRACT:
Method and apparatus for water content determination of soil-water mixtures and of other materials through the use of microwave energy to rapidly dry the material being tested, drying and water content determination being controlled in a preferred embodiment by a computer interfaced with a microprocessor of a digital microwave oven. The invention preferably includes a digital microwave oven mechanically interfaced with a precision digital balance, the oven and balance being operatively interfaced with the computer. As drying in the microwave oven progresses, the computer monitors weigth loss of the test sample as indicated by the balance and controls microwave power levels according to program instructions. The invention is thereby capable of providing rapid, precise and repeatable water content determinations of suitable samples.
