A Marchand et al. Appl Microbiol. 1974 May.

Abstract

A new type of biophotometer is described. Very precise and reproducible measurements of bacterial concentration can be performed at 3-s intervals for each of 32 simultaneously developing bacterial cultures. The large number of results is handled with modern data acquisition and computer-processing techniques.
