FIELD: technical optics. ^ SUBSTANCE: the fluorometer-turbidimeter has the first and second light connected respectively to the first and second sources of exciting voltage, first and second photodetectors with outputs for connection to the system of transmission and registration of the results of measurements, the range of the light wave-lengths registered by the second photodetector is overlapped with the range of the light wave-lengths radiated by the first light source, the first and second sources of exciting voltage are connected to the switch outputs, which are also connected to the inputs of the system of transmission and registration of the results of measurements, the direction of radiation of the light flux by the first light source intersects the axes of sensitivity to light of the zones of the first and second photodetectors. ^ EFFECT: provided measurement of turbidity of liquids. ^ 2 cl, 5 dwg
