Abstract of Disclosure An indicator which is suitable for measuring a body temperature has a generally planar member shaped for retention against a very small outer surface of a body. A temperature- sensitive material is visually activatable within a predetermined temperature range. The temperature-sensitive substance emits, reflects or refracts visible radiation to indicate the temperature. The color sequence in normal white light progresses from tan through red, green and blue and ultraviolet on temperature activation, the color red normally being the first easily visible response when the temperature reaches its responsive range. Thereafter, the color falls off and tends to remain n blue color after the temperature moves above the activation range. An optical filter visually blocks out the blue color to limit the response to the active range.
