    • A device for indicating that an ambient temperature has fallen to or below a predetermined lower threshold temperature. The device includes: a porous membrane having first and second spatially separate zones; a first freezable liquid infused in the porous membrane, the first freezable liquid having a freezing point corresponding to the predetermined lower threshold temperature; a second liquid for contacting the first zone of the porous membrane, the second liquid being immiscible with the first liquid; and an indicator window for indicating migration of the second liquid from the first zone to the second zone. The membrane infused with the first liquid is impervious to the second liquid above the threshold temperature and is permeable to the second liquid at or below the threshold temperature. The device is useful in applications where products degrade below a certain lower threshold temperature.
    • 一种用于指示环境温度已经下降到或低于预定的下阈值温度的装置。 该装置包括:具有第一和第二空间分离区的多孔膜; 第一可冷冻液体,注入所述多孔膜中,所述第一可冷冻液体具有与所述预定的下阈值温度对应的冰点; 第二液体,用于接触多孔膜的第一区域,第二液体与第一液体不混溶; 以及用于指示第二液体从第一区域迁移到第二区域的指示器窗口。 注入第一液体的膜在阈值温度以上不能透过第二液体,并且在等于或低于阈值温度时可透过第二液体。 该器件适用于产品降解温度低于某个较低阈值的应用。
