Ultimate Guide to Thermometers

When someone in your family gets sick, one of the things we check is the temperature to know if a fever has set in and how high it is. When a person has high temperatures for more than three days, then it’s a sign to seek medical attention. This is the reason why having a good thermometer at home, which can provide you with accurate readings is essential.

When you go to the market or when you browse online, you will find many different types of thermometers. And sometimes, it is really difficult to know what kind you should choose. If you do not have any thermometer at home and you’re looking into buying one but can’t decide yet on what kind of thermometer is best for you, then you are in the right place. It’s because today, we are giving you an ultimate guide to thermometers.

Different Types of Thermometers

Choosing the type of thermometer that is best for your family is sometimes confusing. To help you, here are the different types of thermometers you can find in the market, and what each one of them can offer:

Regular Digital Thermometers

Regular digital thermometers use electric heat sensors to get and record body temperature. They can be used in the armpit, mouth, and rectum. Among the three options, armpit temperatures are the least accurate, while rectal temperatures can give the best reading, especially for infants 3 months and younger, and children up to 3 years of age.

For adults and older children, oral readings are typically accurate, as long as the mouth is kept closed while the thermometer is in place. If you want to get two digital thermometers for oral and rectal use, make sure that you label them and that you do not use the same unit for both places.


The good thing about digital thermometers is that they can record the temperatures in just a few minutes or less. However, these may cause discomfort to children, especially when you take their temperatures rectally.

Digital Ear Thermometers


Digital ear thermometers are also known as tympanic thermometers. They use an infrared ray to get the temperature inside the ear canal. When it is positioned properly, it can get temperatures quick, making them more comfortable for children and even adults. This type of thermometer is appropriate for infants older than 6 months, and as well as older children and adults. However, digital thermometers are not recommended for newborns. Also, a curved ear canal can interfere with the accuracy of a temperature taken with a digital ear thermometer.

Digital Pacifier Thermometer

For babies and infants that use pacifiers, you can also use a digital pacifier thermometer to record their temperature. It’s easy to use as your child will just suck on the pacifier until the peak temperature is noted. It’s great because babies will not even realize that you are taking their temperatures. However, it is not recommended for newborns.

Temporal Artery Thermometers


This type of thermometer is usually sold as a forehead thermometer. It has an infrared scanner to measure the temperature of the temporal artery. It is great because it can measure a person’s temperature quickly. It can also be easily tolerated, making it great for infants older than 3 months. And based on research, this type of thermometer can also provide accurate readings for a newborn. However, it can also be more expensive compared to other types of thermometers.

Mercury Thermometers


Mercury thermometers were once a staple in households, especially in medicine cabinets at home. They are thermometers that use mercury encased in glass to measure body temperature. However, this type of thermometer is no longer recommended today because they can break and allow the mercury to escape, which is toxic. If you ever have a mercury thermometer that you need to dispose of, do not put it in the trash. You can instead contact your local trash collection program and ask where the hazardous waste collection site in your area is.

Features to Look for When Buying a Thermometer

There are lots of different thermometer brands out there, so how can you make sure that you are choosing the best one? Well, here are some of the features that you can look for when buying a thermometer:


Accuracy is a very important factor to look into when choosing a thermometer. Make sure that it can provide accurate readings. To do this, pick a thermometer that is scientifically tested and assures accurate results.

Units of Measurement

It is also essential to check if the thermometer you choose offers the option to deliver the results in the unit that you understand well. It can either be in Celsius or in Fahrenheit.
