TempaDOT Oral/Axillary Thermometers are disposable to eliminate time and labor spent on the disinfection, recalibration, recharging, and repair of electronic and tympanic units and eliminate the expense and risk associated with toxic mercury cleanup and disposal; the lack of risk of toxic mercury exposure makes this thermometer a nontoxic and safe choice for patients of all ages. These thermometers are specially designed with an adhesive strip to hold them in place in the axillary region, and each dot changes color from tan to blue at a specific temperature relative to the melting point of the chemical mixture in the dot; the number of dots that fire is dependent upon the patient's temperature.
