Abstract

Device for monitoring the level of the condensate collected in the measurement cylinder of a standardized distillation apparatus for automatically distilling liquid specimens, characterized in that it comprises: on the one hand, a double optical barrier emitting a central beam centered on the measurement cylinder (1), so as to allow detection of the part below the meniscus, and an eccentric beam offset with respect to the central beam and located close to the wall of the measurement cylinder (1), so as to allow the part above the meniscus to be detected; and, on the other hand, a fixed optical barrier intended for counting the drops of condensate falling into the measurement cylinder (1) during distillation.
