PURPOSE:To eliminate an entry mistake by dispensing with the manual work for recording temp. at the time of the drawing of data, by automatically performing the measurement of temp. along with the measurement of a wt. and selecting wt. and temp. measured values to print the selected one by a printer. CONSTITUTION:A change-over device 4 is closed to a B-side when temp. is measured. The environmental temp. in the vicinity of an article of which the wt. must the measured is detected by a temp. sensor 2 to be outputted to a voltage processing circuit 3. The analogue temp. signal from the voltage processing circuit 3 constituted of an operational amplifier and a resistor is converted to a digital signal by an A/D converter 5 to be inputted to a display device 6 and a printer 7. Because the signal showing that the change-over device 4 is closed to the B-side is inputted to the display device 6 and the printer 7, a measured value and a unit deg.C are displayed on the display device 6 and printed beside a wt. measured value previously printed by the printer 7.
