Abstract: This invention relates to a colorimeter with a light source which through a sample to be investigated illuminates a photoelectric transducer, the output of which is connected to a measuring device for measuring the intensity of the transmitted light. The light source is operated from a supply source which is effective to intermittently energize and de-energize the light source, the de-energized periods of the light source being at least as long as the energized periods.
