Abstract: An apparatus including a recording switch for recording a temperature of an object; a judging unit that measures the temperature of the object using a sensor at intervals and judges whether a difference in temperatures measured at the intervals is within a range of a pre-set value; a first acquisition unit that records and/or outputs, when a switch-on of the recording switch is detected and the difference in temperatures is within the range of the pre-set value, information including a first temperature measured using the sensor and has become valid by the switch-on of the recording switch; and a second acquisition unit that records and/or outputs, when the switch-on is detected and the difference in temperatures is outside the range information including a second temperature measured using the sensor and becomes valid when the difference in temperatures falls within the range after the switch-on is detected.

Abstract: An apparatus that comprises: a recording switch for recording a temperature of a target object; and a judging unit that measures the temperature of the target object using a sensor at intervals of a first period and judges whether a difference in temperatures measured at the intervals is within a range of a pre-set value, is provided.

Abstract: A measuring unit capable of measuring change in physical quantity, such as a temperature, and incorporating a measuring portion for sequentially recording plural measurement data measured at a predetermined interval in a memory, and a communication portion capable of transferring the recorded plural measurement data in the memory and the period elapsed from the last data measurement to communication. In the measuring unit, only measurement data can be recorded, requiring no recording of the time information. After transferring the measurement data and the elapsed period to a measuring data management apparatus, the measuring data management apparatus is able to obtain measurement time of each measurement data. Therefore, the structure of the measuring unit can be simplified and the capacity of the memory can effectively be used to record the measurement data. Moreover, time required to transfer measurement data can be shortened.
