要約
(EN)
The present invention provides a concentration meter that is capable of high-precision, high-sensitivity, and highly repeatable concentration measurements and causes reduced product cost, increased compactness, and increased simplicity of the structure of a concentration meter used in an organic starting material fluid supply system or the like. The present invention is configured from: a light source unit that emits light at at least two wavelengths having a phase difference; a detection unit provided with at least two light detection units that receive light that has passed through the inside of a fluid pathway and a light entrance unit such that light from a light source unit enters into the fluid pathway of a detector main body; a computation processing unit that performs frequency analysis for the detection signal of each of at least two wavelengths from the detection unit, computes a strength corresponding to the amount of light absorption at at least three wavelength regions of each detection signal, and computes the fluid concentration within the fluid pathway from the light absorption strength at the at least three wavelength regions of each detection signal; and a recording/displaying unit that records and/or displays the computed values of the fluid concentration resulting from the computation processing unit.
