A good thermometer will provide an accurate measurement of any child’s temperature.
Best Baby Thermometer Types
Mercury or glass thermometer
The mercury thermometer, also known as the glass thermometer, was once the standard device for temperature reading. Despite their accurate reading and easy to clean feature, glass thermometers are no longer deemed safe for use as they can break and expose children to mercury. Infant thermometers have come a long way since then. Today, there are a varied selection of thermometers to measure the temperature of a baby.
A fever that is over 100.4℉ is dangerous for children of any age. To get an accurate reading of a newborn baby’s fever, acquire the core body temperature. The rectal thermometer is a good baby thermometer for this. The American Academy of Pediatrics strongly suggests using a rectal thermometer to get an accurate temperature reading for an infant until age three . A pediatrician may also recommend applying a small amount of baby-friendly water-soluble jelly to make the insertion gentler.
The ear thermometer, also known as a tympanic type of thermometer, gets a temperature reading using a sensor that has to be tucked inside a baby’s ear canal. The eardrums release infrared heat waves when infants and toddlers have a fever. The ear thermometer sensor reads these heat waves to get a precise reading. It is less intrusive than a rectal thermometer and still able to provide a precise temperature reading.
According to thermometer reviews, the armpit thermometer is one of the cheapest external thermometers in the market today. Also known as axillary thermometers, the armpit thermometer is placed under a baby’s armpit and reads the temperature using the skin contact.
The axillary thermometer is one of the least accurate measurements of a child’s temperature. Because it reads a child’s armpit temperature only, the reading may vary two degrees or more. Axillary thermometers may also be difficult to use on fussy babies.
The forehead or temporal artery thermometer reads temperature using an infrared scanner. The temporal artery in the forehead generates infrared waves which are scanned by the device for an accurate reading.
To measure temperature, swipe it across a baby’s temporal artery in the forehead, and the reading will appear on the screen in a matter of seconds. This thermometer is used throughout many hospitals. However, it is on the higher end of the price scale.
Infrared forehead thermometer
The infrared forehead thermometer, like the temporal artery thermometer, is another type of temperature reading tool that is unobtrusive. The device measures the infrared energy emitted from the skin around and above the eyebrow area.
Unlike the temporal artery thermometer, this device enables a temperature measurement without having to make skin contact. It is fast and easy to use, but these types of thermometers can be very expensive.

The backlight display of the temperature reading tool will change depending on the severity of the artery reading. It is the most expensive artery thermometer, double the price of most armpit and mouth temperature reading devices. However, its discreet and strategic technology is worth the hype. | Price $45
