Abstract
From a vessel in which micro-organisms grow in a liquid medium containing gas bubbles, a sample is withdrawn into an exterior measuring chamber by means of suction. Gas bubbles are allowed to escape from the sample and thereafter the opacity or turbidity of the sample is measured by passing a light beam through it.
