Quatre \u00e9chantillons de poudre de cacao : brun clair, brun moyen, brun fonc\u00e9 ? L’\u0153il nu ne fournit pas de valeurs chromatiques fiables. <\/em><\/p>\nC’est pourquoi une quantit\u00e9 g\u00e9n\u00e9reuse de poudre de cacao est plac\u00e9e dans une cuvette ronde en verre de 64 mm. Une \u00e9paisseur de couche suffisante minimise les effets de la lumi\u00e8re ambiante incidente et garantit des mesures pr\u00e9cises. <\/p>\n
On tape d\u00e9licatement la cuvette sur une surface dure pour que la poudre se d\u00e9pose un peu, puis on la place sur le diaphragme pour que la poudre puisse \u00eatre mesur\u00e9e \u00e0 travers le fond en verre de la cuvette. (Veillez \u00e0 ne pas mettre de poudre sur l’ouverture du diaphragme). <\/p>\n
Il suffit d’appuyer sur un bouton pour d\u00e9clencher la mesure de la couleur et afficher directement les valeurs mesur\u00e9es sur l’\u00e9cran.<\/strong><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=\u00a0\u00bb4.16″ background_size=\u00a0\u00bbinitial\u00a0\u00bb background_position=\u00a0\u00bbtop_left\u00a0\u00bb background_repeat=\u00a0\u00bbrepeat\u00a0\u00bb locked=\u00a0\u00bboff\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb][et_pb_column type=\u00a0\u00bb4_4″ _builder_version=\u00a0\u00bb4.16″ custom_padding=\u00a0\u00bb|||\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb custom_padding__hover=\u00a0\u00bb|||\u00a0\u00bb][et_pb_text _builder_version=\u00a0\u00bb4.24.3″ text_font_size=\u00a0\u00bb18px\u00a0\u00bb header_3_font=\u00a0\u00bb||||||||\u00a0\u00bb background_size=\u00a0\u00bbinitial\u00a0\u00bb background_position=\u00a0\u00bbtop_left\u00a0\u00bb background_repeat=\u00a0\u00bbrepeat\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb]<\/p>\n
