Tempa(dot)DOT thermometers are accurate, convenient, versatile and economical body temperature measuring devices. Clinically accurate oral body temperature can be obtained in 60 seconds and axillary temperatures in three minutes. Tempa(dot)DOT thermometers use a dot sensor matrix consisting of temperature-sensitive indicating dots. Each dot changes color from tan to blue at a specific temperature relative to the melting point of the specific chemical mixture of the dot. Each dot changes color at a temperature of 0.2°F or 0.1°C higher than the preceding dot. Body temperature is read from a numerical temperature scale. Tempa(dot)DOT thermometers are sensitive to environmental temperature - see storage conditions.
