Shopping guide

If you think that a guide to buying the best thermometer will be useful to you, you have come to the right place, since here you will be able to know what those aspects are that are recommended to be considered in order to take advantage of the money and invest in the product with the most appropriate price-quality ratio for meet your needs.

thermometer type

The type of thermometer is one of the characteristics that can most influence how much it costs, so if you are looking for an economical model, it is recommended that you take into account the utility that you are going to give the equipment.

Today, thermometers are used in a wide variety of settings, from home to professional use. For example, you can find models for health care, as well as for checking the doneness of meat. In addition, some teams work with wireless systems that do not even require direct contact with the object to be analyzed, which allows temperatures to be measured from a safe distance.

Likewise, you should consider that, in a comparison of thermometers, the type also defines its usefulness, which is why you should determine in advance if you are going to buy one for personal use, to measure the temperature of the environment, for your kitchen or to work. This will make it easier for you to focus your attention on the right guy.

device design

The design of the thermometer is another feature that has a great influence on the purchase decision of many users, especially if it is a model to measure the ambient temperature.

Fortunately, the market offers a wide selection of brands, models and types of thermometers, so if you look carefully, you should have no problem finding the one that looks best in your home.

However, if you prefer, you can also choose discreetly designed room thermometers that you can simply keep in your child’s room or on your nightstand to help you learn how to better manage your heating or air conditioning at home.

Therefore, we advise you to pay special attention to the size of the thermometer, as well as its ease of reading, especially if you want to purchase a mercury model.

Range and resistance

The measurement range of a thermometer can practically determine its usefulness, which is why it is an extremely important aspect to consider so that you can invest in a practical model that allows you to carry out your tasks more easily.

In the case of environmental thermometers, we advise you to choose products that have ranges according to your place of residence if that is where you are going to place it. In general, it is quite easy to find equipment with wide ranges that work with degrees below zero or above average in summer, being useful for different areas of the house.

Regarding the resistance of the thermometer, it could be said that, if you are going to acquire a piece of equipment to install it outdoors, you should make sure that all the components are made of materials that are resistant to the elements of the weather. This will prevent it from showing signs of wear such as oxidation or cracking of the casing due to constant temperature changes or humidity.

Additional functions

In the case of digital thermometers, it is likely that you can enjoy some extra functions if you choose a device with the appropriate capacity for it. For example, there are models that, in addition to offering you information about the temperature, can also provide data about the humidity, being very useful for the home, mainly the children’s room.

By using this type of thermometer to have stricter control over the parameters of the environment at home, you could minimize the risk of allergies, the appearance of mold, among other ills.

On the other hand, if you buy a thermometer for professional use, we advise you to look at equipment that has built-in memory systems for data storage, since this way you can later evaluate the results without having to write them down as you go.

Installation and use

Last but not least, the installation and the very use of the thermometer itself. First of all, you should get a piece of equipment that you can easily place where you want, either hanging or resting on a table. To do this, you must take into account the aspects mentioned within the design category. You can check if it has a hole in its casing, a bracket, magnets, among other means of domestic installation.

Apart from this, since some digital thermometers can offer extra functions, it would not hurt to analyze the general management of the equipment system to avoid complications later.

Frequently asked questions


Q1: How to use a thermometer?

This will basically depend on its type, be it digital, mercury, personal, environmental, among others. In case you have one to measure the ambient temperature, you will first have to choose where you are going to place it, taking into account if it is suitable for outdoors.

After the thermometer is located, you can wait a few minutes for the mercury to reach the level determined by the temperature of the environment or turn it on if it is a digital one. Depending on your model, it will take more or less seconds to indicate the temperature on your screen.

Also, you should keep in mind that some devices allow you to see the data in degrees Celsius or Fahrenheit, so you will have to choose the format that you know best.

Q2: Who invented the thermometer?

The first predecessors of the mercury thermometer, considered the first for regular use, date back to the time of Galileo Galilei when in 1592 he invented the thermoscope, a piece of equipment that uses the contraction of air when the temperature drops to raise the level of water inside a tube.

But it would not be until the 1610s when the numerical scale for temperature measurement would be incorporated by Santorio Santorio and Francesco Sagredo, although the former is credited as the author of this.

The mercury thermometer, one of the best known types, was invented in 1714 by Daniel Gabriel Fahrenheit, adapting Galilei’s original invention and also creating the well-known and still used Fahrenheit scale for temperature measurement in different types of thermometers.


Q3: Where to buy a mercury thermometer?

Before buying a mercury thermometer, you should know that these have been banned in Spain since 2007 due to the polluting effects they produce if they break.

However, it is possible to purchase them for home use and you can find them in pharmacies, online stores, supermarkets and many other places. However, to avoid risks, we advise you to consider digital measurement models first.


Q4: What happens if you touch the mercury in a thermometer?

The risk posed by mercury in a thermometer has both health and environmental effects, so if your equipment breaks, you shouldn’t touch the liquid metal with your bare hands, as it sticks and can stay on. the skin for a long time.

Likewise, it is not advisable to pour mercury down sinks, since the chemical is likely to end up in natural landfills and can affect the health of fish and plants or even the entire ecosystem.

Therefore, although household thermometers do not usually have lethal amounts of mercury, we still advise you to use disposable gloves and adhesive tape to be able to collect all the mercury. At the same time, you should ventilate the room, then pour the chemical into a non-metallic container and take it to a special waste dump.

Q5: How does a mercury thermometer work?

A mercury thermometer has a tube inside filled with this liquid metal which changes its molecular composition when in contact with heat.

Therefore, when a thermometer of this type perceives heat, the mercury inside expands, causing it to travel through the tube. Thus, when you reach the maximum level and verify the numerical scale, you can know the temperature of a person, object, element or place.


Q6: How to know if a digital thermometer works well?

One of the most reliable ways to determine the accuracy of a digital thermometer is by comparing it to a mercury thermometer. Although the latter have been banned in recent years due to contaminants, their accuracy is considered higher compared to digital ones.

Therefore, if you have one at hand, this could be the best alternative to verify that the digital model is giving the correct results.


Q7: How to make a homemade thermometer?

To make a homemade thermometer you will need a bottle, alcohol, food coloring, a straw, plasticine and water.

The first step is to add both water and alcohol in equal parts to the bottle, filling it approximately ¼ full along with a few drops of the colorant of your choice. Then, place the straw in the mouth of the bottle, preventing it from touching the bottom and sealing everything with the plasticine.

Place the bottle near a heat source, such as the kitchen, for example, and you will notice how the liquid begins to rise through the straw due to the same reaction as mercury: dilation. Make the measurements to add the numerical scale and thus be able to know the ambient temperature of your home.
