<p>An over temperature alarming display apparatus. The apparatus includes a first sealed transparent container which has a constant containment and a second sealed transparent container which has a variable containment. The first and second container is communicated each other by a thin guide pipe in a section of which there is liquid. There is some alarming display material in the first and second container respectively which receives the liquid flowing from the thin guide pipe and then occurs a color changing effect. The air in the first and second container occurs dilation by heating and shrinking by cooling due to the change of the ambient temperature, thus pushes the liquid to move in the thin guide pipe. Then the moving liquid flows to the alarming display material in the first container at the lower limit temperature value and/or flows to the alarming display material in the second container at the upper limit temperature value.</p> |
