Abstract
A moisture detection meter (10) has a sensing head having a single chamber (11) with an open top. A dielectric resonator member (14) is provided in the chamber. The sensing head also has a field generator (17) to generate an oscillating electric fluid in the chamber. The resonator member (14) and the field interact to produce at least one field component which is directed out of the open top of the chamber to interact with stock passing over the sensing head. A detection device is also provided to detect the frequency of resonance of the field compact after interaction with the stock and an indicator device is provided so as to give an output indicative of the moisture content of the stock.
