The Digital Thermometer utilizes measured thermistor resistance and a microcontroller unit to determine and display human body temperature. Changes in the probe temperature due to oral or auxiliary contact correspond to changes in resistance. The probe Temperature values are digitally displayed on an LCD screen in 0.2 degrees Fahrenheit increments. The measurements do not account for a probe cover. The user contacting materials are Stainless steel and Acrylonitrile Butadiene Styrene (ABS). The Digital Thermometer includes 3 models: DT001, DT007 and DT008. The differences of these models are in appearance and specifications. All of them have the samebasic functions: - Precision of 0.1°C for measurements between 35°C and 39°C for measurement - Data displayed in Celsius - Automatic stop (energy saver)
