Temporal thermometers provide quick readings, within several seconds.Some are known as non-contact infrared thermometers.įorehead thermometers that require no physical contact have become very popular for use in venues such as airports, stores, and stadiums.įorehead temperature readings run around 1☏ (0.6☌) cooler than oral temperature readings. Make sure you have the right type of batteries on hand for your device and that you understand how to change them, so you’re not left scrambling in an emergency.įorehead thermometers use infrared sensors to measure the temperature of the superficial temporal artery, which is a branch of the carotid artery. Batteries in thermometers should be replaced periodically.This may require the purchase of two thermometers, which should be labeled. You shouldn’t use the same thermometer for both rectal and oral readings.Rectal readings may be uncomfortable to get for infants and small children.Oral readings won’t be accurate if they are taken too close to eating or drinking, because results may be skewed by your food or drink’s temperature.For this reason, rectal readings are considered to be the most accurate for infants and small children. In order to get an accurate reading from oral use, the tip of the device must be placed under the tongue with the mouth completely closed. Benefitsĭigital thermometers provide accurate readings in about 1 minute or less. Rectal thermometers run ½ to 1☏ (0.6☌) warmer than oral readings. When assessing digital thermometer readings, keep in mind that armpit (axillary) temperature runs about ½ to 1☏ (0.6☌) cooler than oral readings. They can be used to take temperature readings in the mouth, rectum, or armpit. Digital thermometers work by using heat sensors that determine body temperature.
