<p>PROBLEM TO BE SOLVED: To reduce the size and weight of the instrument and to improve the measurement accuracy thereof by covering a measuring section with a heat insulating material, arranging temp. sensors in the photoirradiated part of a living body or a detecting section for diffused and transmitted light and calculating the concn. of glycol, etc., in accordance with the measured temp. and light attenuation degree. SOLUTION: The hole to be inserted with the finger which is the measuring section of the living body 1 of a casing 3 is provided with the cylindrical heat insulating material 2. This casing 3 is internally provided with light sources 5a to 5c, an optical sensor 8, a signal processor 12, etc. Further, the size and electric power of the instrument are reduced by using a digital numerical display panel using a liquid crystal panel. The temp. sensors 10, 10' are so disposed that the finger comes into contact therewith and the living body 1 and the temp. sensors 10, 10' come into tight contact with each other when the finger is inserted into the casing 3, by which the temp. of the finger is measured. The heat insulating material 2 eliminates the influence of the outdoor air temp. and maintains the temp. constant. Then, the temp. distribution information in the range where the light transmits and diffuses in the living body is obtd. by the temp. measurement at the two points on the surface.</p> |
