OPTOELECTRONIC PHOTOCOLORIMETRE Russian patent published in 2011 - IPC G01N21/03 

FIELD: physics.

SUBSTANCE: optoelectronic photocolorimetre has a driving generator, n light-emitting diodes, n measurement photodetectors which are optically connected to the light-emitting diodes, a photoelectric signal processing unit and a cuvette made in form of a sphere with a cylindrical cavity in which a silver plated rod is fit and attached by posts to the walls of the cylinder. The device is put into a housing in a stationary position. There is also a funnel and tap for covering and allowing the control liquid into the cuvette, which are simultaneously attached to the cuvette and the housing and a switch for switching radiation onto one of the optocouples.

EFFECT: high sensitivity of the optoelectronic photocolorimetre and simplification of its design.
