Furthermore, it has an internal memory capable of storing up to 40 readings, while the LCD display has the characteristic of changing color according to the recorded temperature. Very comfortable to hold in the hand just like a small remote control, thanks also to the presence of a cover on the probe which further increases its handling.

Thermometer with Gima glass

Although the models reported so far are all able to measure the temperature in an optimal way, some may prefer the classic glass solution which, even today, is the one that guarantees the best accuracy, to the disadvantage of a reading significantly slower than an infrared model. The model we propose does not contain mercury, but an alloy of gallium, indium and tin, which are completely non-toxic materials. In addition, this is a certified medical device, a factor that may prompt many to evaluate their purchase.

How to choose a thermometer for fever

Thermometers are rather simple instruments, therefore the factors to be taken into consideration before a possible purchase are minimal and can be summarized in a single aspect, namely that of the type.


As you have already read in the initial stages of this article, fever thermometers can be of 3 types; glass, digital and infrared, each with different characteristics and points in favor that we are going to report below, with the aim of helping you to choose the most suitable one for you.

Glass thermometer: it is the classic instrument that we have all used it at least once. Although glass models are used much less today than in the past, they are the most reliable on the market, which is why they should be taken into consideration by those who want to have the utmost certainty that the reported temperature is the correct one. On the other hand, it takes several minutes before you know your body temperature, which can be annoying for little ones. Digital thermometer: the accuracy of the detection is substantially the same as a glass thermometer, with the advantage of having a convenient display in which the temperature is reported. Also in this case the waiting times are quite long, but many recent solutions will allow you to save the last readings, useful for remembering or comparing the values ​​with the previous ones. Infrared thermometers: they are the ones that have taken over and the reason is simple, since they can read the temperature of your body within a few seconds, if not even in tenths of a second. This means that these models offer extreme ease of use and boast additional functions such as an alarm when a high temperature is detected, a memory capable of saving many measurements and the ability to set the thermometer based on age. However, this type of thermometer tends to be the least accurate, although the error threshold is often limited to just a few tenths.

How to use a fever thermometer

The steps required to properly use a thermometer vary depending on the type of thermometer you are using. Usually, you should follow the manufacturer's directions to make sure you are using it correctly. In any case, place the thermometer on or near the area of ​​the body where you intend to measure the temperature and keep it still for a few seconds until the device emits an acoustic sound that confirms the reading.

Digital thermometer

A digital thermometer can be used in three different ways:

Oral: the thermometer is placed under the tongue. This method can be used by both adults and children, and it is recommended to apply this method from 4 years of age, so that the child can keep it firmly in the mouth. Rectal: The thermometer is inserted into the rectum. This occurs mostly in infants, but can be used in babies up to 3 years of age. The rectal temperature can also be measured in children over 3 years of age, but it may prove more complicated due to the child's reactions. Axillary: the thermometer is placed in the armpit when the temperature cannot be measured safely orally. This method is not as accurate as oral or rectal, but it is great for a quick check.

Ear thermometer

As you can easily guess, this thermometer measures the temperature inside the ear through infrared heat. For best results, be sure to follow the instructions in the device description, where it is often advised how to position the tip correctly. For babies and adults, thermometers that measure the temperature in the ear can be faster and easier to use. However, they are not recommended for those under 3 months of age. Also, they should not be used if there is too much ear wax or ear pains are present at that time.

Forehead thermometer

Forehead thermometers are often used to measure the temperature of the ear. body, but they may not be as reliable as digital thermometers and are usually more expensive. They are placed on the temporal artery of the forehead and measure the temperature through infrared heat from the head.

Mercury thermometers are not good, why?

As mentioned in the early stages, you shouldn't use your old glass thermometer that contains mercury for a variety of reasons. The first is that they are difficult to read and did not always provide accurate information. Another important factor that should keep you away from this type of thermometer is that mercury could harm your health. This can happen if the glass breaks, causing the mercury to escape. If you still have a mercury thermometer, we recommend that you dispose of it properly at specific hazardous waste locations. Modern glass thermometers no longer use mercury, but most people prefer to rely on digital thermometers because they are more durable and flexible.

How and when to clean the thermometer?

thermometer should be cleaned before and after using it. You can use soap and water or alcohol to clean the tip of the digital thermometers, then rinse with warm water. If you are using the rectal method, be sure to clean it thoroughly and label it. Afterwards, keep it in a specific place so that you can immediately recognize that it is the one used to measure the rectal temperature and not to confuse it with the oral or axillary one.

Our advice is always to read the instructions given. in the package, although you can almost always clean the tip with alcohol. The underside and handles can be cleaned with disinfectant instead. However, be sure to use water to clean the disinfectant so that it does not damage the handle of the thermometer. If your thermometer comes with a case, use it to store it in a suitable place. Finally, we suggest keeping the thermometer in a dry place, where it is not exposed to large changes in temperature.
