摘要： A salinity measuring apparatus to determine salinity of food includes a salinity sensing unit including a pair of measuring electrodes and a capacitor, a switching unit to switch a voltage of the capacitor of the salinity sensing unit, and a control unit to provide a pulse signal with a constant frequency to the switching unit and to determine the salinity of the food which is in contact with the measuring electrodes of the salinity sensing unit based on when the voltage of the capacitor reaches a reference voltage. 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.

摘要： A storage container with a sensor device to detect a state of food contained in the storage container and a refrigerator having the same. The sensor device is separably mounted to the storage container. The sensor device includes an electrode terminal usable not only to achieve a charging operation, but also to achieve a salinity measuring operation. Thus, the sensor device has user convenience while having a compact size.
