Abstract
A temperature indicator is disclosed which includes a housing providing a transparent window. A bimetal snap disc is located in the housing and is movable from a position spaced from the window to a position immediately adjacent to the window upon reaching a predetermined temperature. The housing includes an opaque fluid which obscures the face of the snap disc from view through the window when it is spaced from the window but allows viewing of the face of the snap disc when immediately adjacent to the window. A suitable indicia is provided on the snap disc which provides an indication that the snap disc has operated by being exposed to the critical temperature. The snap disc is arranged so that it remains in the operated position after being exposed to the critical temperature involved.
