Digital Thermometer

Digital Thermometer

A digital thermometer is used to get the temperature of a person. There are a few different types, but they all show the reading on a small LCD display. The most basic one is similar in shape to the mercury thermometer and is also used similarly, it can either be placed under one's tongue or inside their armpit.

The other type includes a tympanic digital thermometer that has a bauble which is placed inside one's ear and gets a temperature reading from there. This is used to get a reading closer to the brain.

Another is the infrared thermometer that is pointed at your forehead and gets a reading without any touch. This is useful if a no-touch policy is in place.

Accuracy

Digital thermometers are not considered to be as accurate as the older mercury thermometers. There is a variation of ±0.2 °C (±0.35 °F) when new. One should regularly calibrate it to keep it within a minimal range of possible inaccuracy. 

Comments

A digital thermometer can cost from a mid to high range depending on the specific type and brand. Mothercare and Beurer are the known producers of digital thermometers.
