A Portable, Self-Contained Digital Thermometer

摘要

The digital thermometer was designed and developed in response to an Air Force requirement for a special multipurpose thermometer. The instrument is 3 in. wide, 4.5 in. long, and 1 in. thick. It weighs 13 oz. including the self-contained silver zinc batteries. One temperature range incorporated in the unit measures temperatures from 32 to 212F., with an accuracy of 1 degree. The second range measures oral temperatures from 95 to 105F., with 0.1 degree accuracy. A number of interchangeable temperature sensors are available for measuring oral or skin temperature, air temperature, liquid temperature, and the temperature of metal surfaces. The time required to take an oral measurement is less than 1 minute. Immediate, accurate readout of temperature is possible because of the digital feature. The thermometer, because of its portability, size, accuracy, and fast readout, holds potential promise for use as a general instrument for clinical medicine. (Author)
