Abstract

A temperature indicator for indicating the temperature condition of an object while subjecting the object to an external temperature environment. The temperature indicator includes a substantially transparent outer shell containing a substantially transport modeling structure, which includes a plurality of heat receiving elements, for modeling the thermal diffusivity of the object. The indicator also includes a temperature measuring device in thermal contact with the modeling structure for measuring the temperature within the outer shell to thereby indicate the temperature condition of the object. The outer shell including first and second sections which apply a compressive force to the modeling structure when the first and second sections are secured together to thereby confine the modeling structure within the outer shell.
