ABSTRACT:
A time-temperature indicator, particularly adapted for use with closed sterilizing or cooking vessels, such as pressure cookers and sterilizers, to indicate at what temperature and for how long material contained within the vessel has been heating or cooking, is disclosed. The indicator uses a material such as a thermochromic material which changes color at a predetermined temperature, and is constructed to provide readings around a 360.degree. angle. The indicator may, for example, be constructed as a knob on the lid of a pressure cooker or sterilizer or the link or may be attached to or as a replacement for an existing knob.
