Abstract
A radiometric analyzer for measuring the characteristic values of a sample by radiation includes a plurality of radiation measuring subsystems having different ratios of sensitivities to the elements of the sample and linearizing circuits having inverse function characteristics of calibration functions (calibration function while varying the density in a constant content ratio of the sample) which correspond to the radiation measuring subsystems and a weighing adder for operating a desirable linear combination of the outputs of the linearizing circuits and operators for operating between two or more different linear combinations.
