Apparatus adapted to perform optical measurements on dye baths, comprising a cell (1) with an inlet (10) and an output (11) to allow the dye bath to flow through the same cell (1), light emitting means (12A, 12B, 12C) adapted to produce a light intended to pass through the dyeing bath and placed in a predetermined area of the cell (1), light-detecting means (13A, 13B, 13C) adapted to intercept the light produced by said light emitting means and placed on the opposite side of the cell with respect to the latter, and programmable means (2) adapted to drive said light emitting means (12A, 12B, 12C) and to process electrical signals emitted said light-detecting means (13A, 13B, 13C) on the basis of a predetermined processing program. Said light emitting means (12A, 12B, 12C) are associated with additional light- detecting means (14A, 14B, 14C) placed on the same side of the light emitting means (12A, 12B, 12C) with respect to the cell (1) and also connected to said programmable means (2) that receives the signals emitted by the additional light-detecting means and processes them according to the predetermined processing program. |
