Shopping guide

Barometer models are varied, so it will not be so easy to find the right product for you. Therefore, we have prepared this guide to buy the best barometer, with which you will be able to know the main qualities of this type of utensil.


If you make a comparison of barometers, it is best to know the different types that exist. Among them, we mention the aneroid barometers, which are analog and do not require mercury or batteries, so they are a bit more ecological.

These barometers work thanks to a vacuum capsule that they carry inside, which is unit at the same time to a series of gears that increase their movement, making the needle move. If the atmospheric pressure drops, the capsule decreases in size and the needle turns to the left. On the other hand, when the pressure rises, the capsule swells and, consequently, the needle turns to the right.

Another type of barometer is the digital one, which requires batteries and usually has a screen where you can see the data. Digital barometers have various configuration buttons and offer other functions such as altimeter or temperature reading. Among the digital barometers are those that have a USB connector, these are connected to the computer to transfer all the previously recorded data.

On the other hand, there are independent barometric sensors, which you can only use when you install it on an Arduino board. In other words, these barometers are special for home electronic projects. For example, if you are making a drone with Arduino or Raspberry Pi and you want to measure the height of the drone when it is flying, you must mount a barometric sensor of this type. This sensor is a small card, which does not weigh much or take up too much space in the drone.


Before asking yourself how much a certain barometer costs, it is best to review this point, since the measurement is not the same in all sensors of this type. For example, some offer their data in different units of measurement, among which hPa, mbar, psi and mmHg stand out.

Some barometers offer many measurement options, but are more expensive, so you will have to spend more money. However, due to the wide variety of barometers on the market, it is possible to get a good and cheap model.


Comfort is another quality that you should check when buying a barometer, because if it is easy to store and transport, you will have no problem using it at any time or place. For this, it is important that the product comes with a case or carrying case, so that it is protected from possible bumps or scratches. Probably, if the barometer you are going to buy comes with this accessory, it will last you a long time.


A barometer that has very small data will not be practical for you, especially if you have any vision problems. Therefore, it is better to buy a model that has the numbers and other big data, which you can see with the naked eye. In this sense, the barometers whose numbers are closely linked are also not the most appropriate.

Another important aspect related to the visibility of the barometer is lighting. Of course, this quality almost always only exists in digital barometers, so if you buy an analog model, it probably won’t come with lighting.

But this is not all, because the digital barometer should also offer you an option to turn on the screen light only when necessary. Otherwise, it will discharge very quickly and you will have to buy batteries often.  


This is another important aspect, the functionality, since the barometer does not always only offer the reading of the atmospheric pressure. Sometimes, depending on the model you choose, it may have an altimeter function, as well as a temperature and humidity reader.

If the barometer has several functions, you can use it in various activities or engineering works, so do not forget this quality when you are choosing a certain model.

Temperature is displayed on multifunctional barometers in two ways, °F and °C, so make sure the product you like offers the unit of measure you require for your projects.

Frequently asked questions

Q1: How to use a barometer?

The barometer is not complicated to use, you just have to calibrate it before you start. The aneroid barometer has a calibration screw on the back, so you must use the appropriate screwdriver to turn it as needed.

You must turn the screw depending on the atmospheric pressure of the moment and place. When you turn it you will see that a barometer needle moves. Check the atmospheric pressure of the place where you will start the trip or where you will work at a reliable weather station. 

Q2: How does a clock barometer work?

Normally, the watch barometer shows a history in the form of graphs, so you can take into account the rises or falls in atmospheric pressure while climbing a mountain. This is possible in some watches through the integrated GPS, so many times it will not be as accurate as an analog barometer, since it will depend a lot on satellite coverage.

The best watches have an advanced barometric sensor, but their prices are much higher. These sensors work with the same precision as the vacuum capsules of an aneroid barometer and do not require electricity or a satellite signal, so they will keep you informed anytime, anywhere.

Q3: What is the difference between barometer and pressure gauge?

The barometer is special to measure the atmospheric pressure and open containers, on the other hand, the manometer measures the lower pressure, specifically those of closed objects, such as tanks or pipes. In this sense, if you want to measure atmospheric pressure while climbing a mountain, you need a barometer, but if what you want is to measure the pressure of gas, water or air in a pipe, we recommend a manometer.

Q4: How to interpret a barometer?

First of all, you should know that the barometer generally measures the atmospheric pressure in hPa, that is, hectopascals, however, there are other very common units of measurement such as mbar, which means millibars.

When the needle of the barometer turns to the left it means that the atmospheric pressure is lowering. On the other hand, when the needle turns clockwise, it is informing you that the atmospheric pressure rises. In practice, if you are climbing a mountain and you see the needle turn left unexpectedly, it is very likely that it will rain soon, so take the necessary precautionary measures when that happens.

Q5: Which is better, digital or analog barometer?

Normally, the digital barometer uses batteries, so it requires extra purchases. However, these usually last a long time, especially if you do not use the light that most digital barometers have to see the screen more clearly in dark places. In addition, a digital barometer almost always offers other functions, in addition to detecting atmospheric pressure, for example, altimeter and environmental thermometer.

For their part, analog barometers do not require batteries, so maintenance is cheaper. They also have a vacuum capsule that informs you about the atmospheric pressure at any time and place, being an advantage for long trips in the mountains where there are no stores nearby. However, they do not have light to see the data clearly in dark places.

In other words, both types of barometers have their pros and cons; The decision of which is the best will depend on the one that best suits your requirements.

Q6: How to make a homemade barometer?

You can make a homemade barometer with an empty glass container, for example, the compote. You could also use a glass container like the one that comes with some tomato sauces for pasta or pizza.

You must cover the container with a piece of thin rubber, held with a metal wire. To obtain the rubber you can cut a balloon that people use at parties or birthdays. It is important to leave extra wire to hold a drinking straw over the rubber. The latter will be the one that will move when the atmospheric pressure goes down or up.

Q7: Where to put a barometer?

The barometer can be placed on the dashboard of the car so that you are informed about the atmospheric pressure while traveling. Also, you can mount the barometer somewhere in your house, so that you are informed at all times if a storm is approaching. It is even possible to place it in heating boilers to check if its pressure is adequate.
