By providing the pulse signal with the constant frequency to the switching unit, it is possible to minimize the internal impedance variation of the capacitor and to more accurately measure the salinity of the food. Since a period when the voltage of the capacitor is substantially “0” is present, it is possible to minimize accumulation of ions in the measuring electrodes. | 12-29-2011 |
