ABSTRACT:
Disclosed is a temperature indicating method and device. The device embodies a sealed tube containing a liquid and a float. The tube has markings on the exterior indicating temperature zones or, in the alternative, temperature gradients. The method disclosed includes inverting the tube such that the indicator drops to the bottom of the tube and freezing the device at the appropriate temperature level. In use, the device is placed right side up in a container along with other items for which the highest temperature level arrived at is desired to be known. Upon warming, the liquid in the tube melts and the float drops through the liquid to the freezing level of the liquid. By removing the device from the container and comparing the float level in the tube to the markings on the exterior of the tube, the highest temperature or temperature zone that the contents of the container were subjected can be determined.
