Abstract
The present invention relates to a chemical luminescence-detecting apparatus that is provided with a plurality of optical detectors different in sensitivity in the vicinity of a photometric cell. A ratio of outputs from the optical detectors based on intensity of luminescence is previously determined and stored. Signal processing can multiply an output of a low sensitivity optical detector by a factor determined by the stored ratio to measure the intensity of luminescence so that a conversion value corresponding to an equivalent output from a high sensitivity optical detector may be obtained when the output from the high sensitivity optical detector has become saturated.
