PURPOSE: To indicate the ambient temp. (atmospheric) in which a clock is placed accurately and with a high reliance by furnishing a means to alter the temp. displayed by temp. sensors depending upon whether the clock is put on a person or not.
CONSTITUTION: A means to alter the temp. indicated by a string of precision liquid crystal temp. sensors (the color changing at specified temp.) 18 is equipped with the second temp. graduation (corrective graduation) 28 and installed opposingly to the sensors 18 in the same manner as a first temp. graduation (physical temp. graduation) 20. A second graduation 28 is callibrated so as to indicate the temp. value representing the ambient temp. in case a clock concerned is put on a person. The first graduation 20 is installed on a bazel 6 while the graduation 28 is installed on a clock board 10. The temp. indicated by the clock put on the person is given by the hatched sensors 18 in combination with the graduation 28, and if it is 20°C, a value is indicated in combination with the graduation 20 by the same sensors 18 in the case where the clock is not put on, reading 24°C.
