FIG. 2 is a schematic block diagram showing the specific configuration of the same.

In FIGS. 1 to 3, numeral 10 is a temperature sensor that detects the temperature according to the temperature change of the temperature-measured part, and the thermometer main body 20
It is flexibly attached to via a lead wire 21. Of course, it can also be provided integrally with the thermometer main body 20. Reference numeral 11 denotes an A/D converter for converting the electric signal detected by the temperature sensor 10 into a digital temperature signal.
Temperature information detected from multiple points is stored as temperature data in the memory 41 of the CPU 40, which is the temperature storage means 30. The memory 41 of the CPU 40 also functions as a location data storage means 30 and a time data storage means 50, which will be described later. Therefore, this memory 41 further stores data on each location where the temperature data was obtained (NIL display) and each time data at the time of measurement.
each is memorized.

51 is a clock with a function to display the current time, and the CP
It is disposed inside the main body 20 in connection with U40. However, it can also be arranged on the outer surface of the main body 20. The time at which each of the temperature data was obtained and the time at which the temperature was measured is measured by the clock 51 and stored in the memory 41 as the time storage means 50. At the same time, this time data is displayed on a time display 53 as time display means 52.

Reference numeral 32 denotes a temperature display as temperature display means 31, and this temperature display 32 also serves as a floor display 34 as display means 33 for location data (N11 display), which will be described later. Of course,
It is also possible to separate the floor display 34 from the temperature display 32 to make the temperature display and floor display independent.

Reference numeral 60 denotes a so-called storage/readout mode changeover switch that is operated when storing/reading various data such as measured temperature. When this mode changeover switch 6o is turned to the storage mode) side, the storage mode indicator 61 lights up. and memory switch 62
operation becomes possible, and when the switch is switched to the readout mode side, the successive mode indicator 63 lights up and the readout switch 64 is turned on.
operation becomes possible. Then, in a state where the storage switch 62 is enabled to operate, this switch 62'k
When the ON operation is performed, the aforementioned eccentricity and time data are stored in the memory 41 as the temperature/Nu storage means 3o and the time storage means 5o by reading by the CPU 40. In this case, at the same time, the number (
m) 71 is also read and stored. Each of these data is displayed on each display 32, 34, and 53 so that it can be confirmed.

The temperature measurement location number (Nl) 71 mentioned above is entered in advance in the multi-point entry column 70 for each floor provided in an appropriate space on the operation panel surface of the thermometer main body 20. ), and a number is assigned to each of the multiple locations entered. A group of these numbers 71 serves as the location data, together with the measured temperature data at that location and the time data at the time of the measurement,
