Not all thermometers are equally suitable for every situation. The right choice depends on who it's for (baby, child, or adult), the speed you need, and whether you prefer contactless measurement or contact. We'll tell you about the types and which one to buy.
Types of thermometers
Contactless thermometer (infrared)
Measures forehead temperature remotely, in 1 second, and without touching. It's the most convenient for babies and children and for taking temperature while they sleep, and the most hygienic for multiple people. Ideal if you prioritize speed and convenience.
Digital thermometer
The classic, affordable, and reliable option. Used in the armpit, mouth, or rectum and beeps when finished. Models with a flexible tip are more comfortable and safer for children. Very good precision-to-price ratio.
Large-screen digital thermometer
As reliable as the classic digital thermometer but with large, backlit digits, perfect for elderly people or those with vision problems.
Gallium thermometer (mercury-free)
The modern alternative to the now-banned mercury thermometer. Uses a mercury-free gallium alloy, is very accurate, doesn't require batteries, and is environmentally friendly. Takes a little longer to measure, but it's the preferred option for those seeking maximum accuracy.
Quick chart: which to choose
- Babies and children: contactless infrared or digital with a flexible tip.
- Maximum speed and hygiene: contactless.
- Elderly people: large-screen digital.
- Maximum precision and no batteries: gallium.
- Tight budget: classic digital.
What temperature indicates a fever?
As a guide, a low-grade fever is considered between 37.2 and 37.9 ºC, and a fever is 38 ºC and above. Rectal measurement is slightly higher than armpit. For high or persistent fever, especially in babies, consult your doctor.

Frequently asked questions
Which thermometer is best for a baby?
The contactless infrared thermometer is the most comfortable and hygienic for babies because it measures on the forehead in one second without waking them up. As a contact alternative, a digital thermometer with a flexible tip.
Are contactless thermometers reliable?
Yes, if used correctly: at the indicated distance, on a clean and dry forehead, and without drafts or sudden temperature changes. They are very practical for hygienically measuring multiple people.
Does the gallium thermometer replace the mercury thermometer?
Yes. The gallium thermometer uses a mercury-free alloy, is just as accurate, doesn't use batteries, and is environmentally friendly, making it the recommended alternative to the old mercury thermometer.
At what temperature is a fever considered?
As a guide, a low-grade fever is between 37.2 and 37.9 ºC, and a fever is 38 ºC and above. For high or persistent fever, especially in babies, consult a healthcare professional.
