πlis study was carried out to develop a moisture content(MC) meter using electrical impedance at 1암fz.πle MC meter measures phase-shift with speci외ly designed electrode and electrical circuit.Moisture content was estimated from the phase-shift using relationships between moisture content and phase-shift.Correlation models were acquired by regressing the moisture content measured by oven-dry method, on the phase-shift measured by the MC meter.The result implied that precise moisture measurement with a large sample can be possible in a short time using electrical imped때ce at low frequency.
