Title
(EN) PRINTABLE IRREVERSIBLE MINIMUM TEMPERATURE INDICATOR
(FR) INDICATEUR DE TEMPÉRATURE MINIMUM IRRÉVERSIBLE IMPRIMABLE
Abstract
(EN)
A multi-event minimum temperature indicator that includes a substrate, at least two thermochromic compositions positioned on the substrate, and an optional top layer adhered to the substrate. Each thermochromic composition is positioned on a discrete area of the substrate, and the compositions provide a visual indication of exposure to progressively colder temperatures.
(FR)
L'invention concerne un indicateur de température minimum multi-événement qui comprend un substrat, au moins deux compositions thermochromiques positionnées sur le substrat, et une couche supérieure facultative collée au substrat. Chaque composition thermochromique est positionnée sur une zone séparée du substrat, et les compositions fournissent une indication visuelle de l'exposition à des températures progressivement plus froides.
