          FunctionThis is a thermometer used to determine the highest temperature of air over a certain period of time.

          It works by having a very narrow neck through which the mercury has to push through when it is expanding out of the bulb. As the temperature rises, the mercury flows into the almost horizontal section of the tube, but if the temperature falls, the pressure exerted by the mercury on the capillary due to its weight is not enough to push it through. In order to reset the thermometer, one has to incline it to be vertical, and perhaps shake towards the bulb.
