Title
(EN) COUNTING CHAMBER PROVIDED WITH A REFERENCE AND METHOD FOR MANUFACTURING A COUNTING CHAMBER PROVIDED WITH A REFERENCE
(FR) CHAMBRE DE COMPTAGE DOTEE D'UNE REFERENCE ET D'UN PROCEDE DE FABRICATION D'UNE CHAMBRE DE COMPTAGE POURVUE D'UNE REFERENCE
Abstract
(EN) A counting chamber for optical detection of particles that are present in a fluid, comprising two substantially transparent and substantially parallel plates of material (1, 2), between which the fluid can be introduced. At least one of said plates (1) includes a visible reference (8), which comprises a relief formed on the surface of one of said plates (1).
