ABSTRACT:
A photoelectric arrangement for the determination of a substance spectrally differently absorbing light in a specimen (1) comprising two alternately switched on light sources (2,3) of different wavelengths matched to the absorption maximum or minimum of the substance, two photoelectric receivers (5,6) arranged in such a manner with respect to the specimen that the one receiver (measuring receiver 5) receives light which traverses the specimen and the other receiver (reference receiver 6) receives light of the light sources directly and an electronic control and evaluation circuit following the photoelectric receivers and controlling the light sources for the determination of the different absorption typical for the substance at the two wavelengths, wherein the control and evaluation circuit comprises a light circuit (7,8,10,11a,11b) following the reference receiver (6) for determining light amounts transmitted by the light sources and defining the switchover instant for the light sources on reaching a predetermined amount of light.
