Making sure you purchase the best thermometer for home use is a particularly challenging task. The reason behind this lies in the fact that you have to choose an item that works great with kids and adults, a feature that is hard to come by. Because we want to lend you a helping hand, this following buying guide contains all the information you need to be familiarized with before placing an order.

Contact vs. non-contact models

After one rapid look at the market at the current time, one can easily see that one of the most troubling question thermometer buyers are asking is whether or not they should choose a non-contact model.

While old fashioned thermometers have all the well-known advantages, such as the fact that everybody knows how to use them, the newer non-contact models are also quite feasible. The main advantage that this kind of device has is pretty obvious as contactless means disease-less. However, given the fact that you are going to use the product at home, the chances that a virus or a bacteria is transmitted from one person to another are pretty high on their own.

Another plus for the non-contact thermometer is the fact that it is significantly more comfortable for the `patient`. Thanks to the ingenious design this kind of models comes with, such devices can be easily handled without any type of discomfort for the person feeling under the weather.

Just point the device towards them, press a button and, in a few seconds, you’ll get an accurate reading of the person’s temperature. Therefore, these models are by far faster and, some may say, more precise than the older versions.

Moreover, the non-contact models are usually very practical due to the fact that they can also be used to measure room temperature or even object’s temperature, a function many find useful. This option is quite helpful if you have an infant, as you’ll be able to precisely measure things like the bottle’s temperature or the warmth of the bathing water in order to avoid any unhappy accidents.


Memory storage function

Another great feature you should check out before ordering is the memory storage function that some models come equipped with. Thanks to this function, one can easily go back and see previous readings. As a result, you’ll be able to tell if the family member that you are taking care of is getting better or worse.

There are models that provide up to 32 groups of data enterings, and one could argue that that is enough information to get a clear picture of somebody’s condition.

Moreover, some models also come equipped with an built-in alarm that informs you whether the sick person has the fever of not. Therefore, in case a member of your family has a high temperature, you’ll be able to act accordingly and give him/her the needed medication or, why not, take him/her to the doctor for a specialized consultation.


FDA approval

As any best digital thermometer for adults reviews are prone to point out, safety and accuracy should always be on the must-have list of features when buying an item of this type. By settling for a device that has received FDA approval, one can rest assured that the information provided by it is trustworthy.

The reason behind this statement rests in the fact that the models that have received this accreditation have been extensively tested so as not to cause any harm to the users. And, given the fact that buying a thermometer means buying a medical appliance, this kind of certificate is more or less a must.
