Insert the thermometer stem or probe 2″ into the center of the ice bath and stir gently for another 15 seconds, keeping the stem surrounded by the ice cubes and moving constantly. An accurate thermometer will read 32°F. Dont let the thermometer rest against the ice or youll get a low reading.

Digital thermometers contain a small computing mechanism and a resistor. A change in temperature causes the sensor to notice a change in resistance. The computer converts the difference in resistance into a difference in temperature and offers a digital readout in degrees.

Features. The thermometer displays the temperature within 10 seconds, result displayed is highly accurate. ... The thermometer is water resistant, keeping the thermometer safe even if it is in contact with water.

Among adults, the average body temperature ranges from 97°F (36.1°C) to 99°F (37.2°C). Adults over age 65. In older adults, the average body temperature is lower than 98.6°F (37°C).

Normal body temperature is about 98.6 degrees Fahrenheit (°F) or 37 degrees Celsius (°C). Normal temperature often varies from 1° to 2°F (½° to 1°C). A normal temperature is usually lower in the morning and increases during the day. It reaches its high in the late afternoon or evening.

Generally, the correlation of temperature results are as follows: The average normal oral temperature is 98.6°F (37°C). A rectal temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. ... A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

Digital thermometers provide accurate readings in about 1 minute or less.
