Zusammenfassung:PURPOSE: To provide a low price colony measurer capable of simply and accurately measuring the colonies in the measurement of the colonies carried out in the sanitary examination and biochemical examination of foods, etc. CONSTITUTION: In this device, the signals of light transmitted through an agar medium for the growth of colonies is separated from the signals of light transmitted through the colonies, and the light or the sensitivity of a detector is controlled in response to the signals of the light transmitted through the agar medium. Thereby, the number of the colonies can accurately be measured, even when the kind or thickness of the agar medium is changed.
