    Abstract: PROBLEM TO BE SOLVED: To provide a dental color measurement tool capable of stably holding an artificial tooth at a suitable position with respect to a color measurement device. SOLUTION: The dental color measurement tool 60 disposed opposite an opening portion for capturing light from an artificial tooth 50 to undergo color measurement with a color measurement device includes at least one pair of guide posts 63 and 64 having engaging portions 63a and 64a corresponding to engaging portions on the color measurement device side, and an abutment post 62 disposed between the pair of guide posts 63 and 64 and having a pointed convex shape to which the artificial tooth 50 can be mounted. The abutment post 62 has a color measurement reference surface 62a in a color measurement light axis direction as the vicinity of a focus position of the color measurement device in a photographing state. When performing color measurement photographing, the artificial tooth 50 is mounted to the abutment post 62 to position the front 50a thereof on the color measurement reference surface 62a.

    Abstract: PROBLEM TO BE SOLVED: To provide a colorimeter capable of compiling and analyzing a lot of measurements easily and promptly as well as obtaining accurate measurements of substances to be measured. SOLUTION: The colorimeter 10 comprises a colorimeter main body 11, a cellular phone 12 and an analytical device 13. The colorimeter main body 11 includes four LEDs 15a-15d disposed on the top surface of a pedestal 14 and a cell 16, wherein light emitted from any of the LEDs 15a-15d is set to enter the cell 16. The cellular phone 12 includes an operation part 21, a liquid crystal display 22 and a digital camera 23. The analytical device 13 includes a display 31, a keyboard 32 and a controller 33. The image of the emitted light from the cell 16 taken by the digital camera 23 is displayed in the display 22, and also the image data is transmitted to the analytical device 13 through a radio communication line, and then analyzed by the analytical device to calculate the absorbance of a sample solution in the cell 16.
