Abstract: A measuring apparatus of the present invention is an apparatus by means of which the constituent concentration of a specimen is measured on the basis of the color change in a test material housed in a test piece, which has reacted because of the specimen. The apparatus irradiates the test material which is a test piece loaded in the apparatus's main body and detects the intensity of the light reflected by the test material. A detection signal detected in the above way is sampled in a time period before and after the measurement timing at which the test material changes in color because of the specimen. An average value of the sampled detection signals is determined. The constituent concentration of the specimen is computed by referring to a stored conversion table on the basis of the average value determined in the above way.

Abstract: Provided is a weak luminescence detecting device that is capable of, in luminescence measurements, reducing dark current values and dark current pulse counts, preventing fluctuations in dark current values and dark current pulse counts with respect to temperature, and capturing an optical signal with a large solid angle, and that can, with high sensitivity, detect luminescence without directivity, such as bioluminescence and chemiluminescence. A luminescence measuring device is provided with a plate member to hold a container holder in which a sample is stored, a light detector to detect luminescence in the sample, a temperature control unit to control the temperature of the light detector, and a ventilator to blow air on the light receiving face of the light detector.
