Abstract
A system for detecting the particular chemical constituent of a fluid which comprises a photoelectric conversion device for giving forth an electric signal having an amplitude exactly corresponding to the changed color of an absorptive carrier containing a reagent which results from a chemical reaction between a test fluid and the reagent contained in said carrier; a calibration device for eliminating unnecessary components from said electric signal; a device for comparing an output signal from the calibration device with referential data having preset values to determine the sequential position which the measured degree of chemical reaction between the reagent and the test fluid occupies among the various values of said referential data; a printing device for printing out an output from said comparing device representing the content of the desired chemical constitutent of the test fluid.
