FIELD: analytical methods. SUBSTANCE: invention relates to devices for analyses of components of liquid media employing indicator elements impregnated with reagents changing their coloration when chemically interacted with aforesaid components. Analytic plate has a series of indicator elements impregnated with different reagents and separated from each other by polymer film. Indicator elements are placed in two layers communicating with each other through layer of transparent film, on condition that indicator elements in each layer are laid with gaps between them and elements in one layer are arranged against those in another layer. EFFECT: enabled simultaneous analysis of several components in liquid. 4 cl, 3 dwg, 1 tbl
