Description: Warmmark: This device monitor whether a product has been exposed to temperatures above a predetermined threshold. A red dye is released onto a blotter toclearly indicate the duration of the exposure. Specification of Warmmark
Working principle If this label is exposed in the temperature environment that higher than its reactive temperature, chemical things inside of it will turn to red and start to flow along with inside tube. It has 3 round windows, it takes some time when chemical things flow to every window. Thus, time of turning red can be calculated. Chart below will show that. (The time below refers to the time when the labels are exposed in its activation temperature more than 2°C and then all window change color completely)
