Digital thermometers are medical tool to
measure body temperature where it uses electronic heat sensors and record the
result. These thermometers can be used in the armpit, mouth or rectum. Armpit thermometer
are usually least accurate compared to mouth and rectal thermometers. Rectal temperature
provide best reading for infants especially those newborns and children up to 3
years old while mouth thermometer gives accurate reading for older children and
adults.
The answer is ear thermometer. This is a kind of thermometer
that records body temperature through the ear canal. The ear thermometer was conceived
in 1964 by Dr. Theodor H. Benzinger. Dr. Benzinger functioned from 1947 to 1970
at the Naval Medical Research Institute in Bethesda, Maryland where he studied
temperature guideline and helped make the field of biothermodynamics.
