ABSTRACT:
Method of covering a thermometer which includes forming a total enclosure composed of a pair of coatings covering the stem portion and the bulb portion of the thermometer. A substantially transparent plastic material covering the stem portion of the improved thermometer has an index of refraction which is sufficiently high to allow a user to visually interpret the location of an internally contained heat expandable substance in relation to indicia formed on the stem portion. The bulb section of the improved thermometer is enclosed by a thermally conductive layer. Both layers are joined to form a total enclosure for the thermometer throughout the extended length of both the bulb and the stem portions. Additionally, an increased amount of substantially transparent plastic material is added to the terminal end of the stem portion of the improved thermometer in order to provide a cushioning effect under dynamic loads when the thermometer inadvertently falls to an external surface.
