Abstract
A machine for candling articles, such as hatching-eggs, fed on a so-called hatching frame on which the eggs are disposed in juxtaposed rows, which machine comprises a plurality of light measuring systems each including a light source and a sensor. The light measuring systems are arranged in such an array that the articles to be each measured as they rest on the hatching-frame are shielded relative to each other by adjacent articles.
