| 摘要 |
A photoelectric photometer for light absorption analysis in which a light beam passing through the sample cell is split into three beams of monochromatic light having different wavelengths which correspond to the wavelengths at the peak maximum, i.e., the beginning and the end of the absorption spectrum band, due to the constituent contained in the sample, and the light energy of the wavelength exhibiting the peak maximum is compared with a mean value of the light energies of the other two wavelengths, whereby the absorption degree of the constituent of the sample to be determined is indicated for direct reading.
