の濃度分析計。[Scope of Claim for Utility Model Registration] (1) A light source section that uses visible light as a light source, a light transmitting section that transmits this visible light through an optical fiber, and a transparent measurement that holds a sample liquid so that this transmitted light can be transmitted. A tube, a light-receiving section in which the transmitted light of the transparent measuring tube and the optical axis of the received light coincide with each other, a measuring section that conveys the received light with an optical fiber, and the received light is divided into three primary colors, that is, R (red).
, G (green), and B (blue) compositions, and detects the amount of change in visible light before and after the measuring section by color difference. (2) The concentration analyzer according to claim 1, wherein the concentration analyzer is characterized in that the inner peripheral surface of the transparent measuring cylinder holding the sample liquid in the measuring section is cleaned by sliding it with a piston-shaped wiper. . (3) Separate the measuring section into a light transmitting measuring section and a light receiving measuring section, and determine the length of a transmitted light extension tube that connects the light transmitting measuring section and the light receiving measuring section so that the optical axes are aligned. 3. The concentration analyzer according to claim 1 or 2, wherein the concentration analyzer is characterized in that the transmission distance of the light transmitted through the sample liquid can be adjusted by making appropriate settings. (4) The light transmitting tubes of the optical fibers for transmitting and receiving light in the measuring section are made into double concentric cylinders, and reflecting mirrors are arranged oppositely and apart from each other at the ends of the double concentric cylinders. The concentration analyzer according to claim 1, wherein the optical axes of light transmission and light reception are aligned, and a cell containing a sample liquid is placed on the reflecting mirror.
