The WarmMark Long Run is a cost-effective and disposable temperature-sensitive indicator that monitors temperature during transit and storage. Capable of providing users with visual alerts when goods are exposed to unacceptably high temperatures, it also features an indicator window, allowing users to observe the duration of exposure. The sticker label can be fixed directly onto products or their packaging to act as visual evidence for exposure to unacceptable temperature conditions, prompting users to inspect the product quality. If the WarmMark Long Run indicator stays white, the product has not been exposed to high temperatures. However, if the temperature climbs beyond a specific threshold, a red dye will move through the window with time. If the temperature then returns to the threshold, the dye will stop moving. Therefore, indicating to handle how long the product has been above the threshold temperature.
