How to choose your hygrometer

It is not always easy to find the right hygrometer among the many models available on the market. Nevertheless, you can simplify your choice based on the criteria below.

#1 - Level of accuracy

The level of accuracy is certainly one of the most important criteria when you are about to buy a hygrometer. You can have a higher or lower accuracy depending on the use you will make of the measuring instrument. If your objective is to have an estimate of the hygrometry inside your dwelling, you can opt for a model whose precision is included between 5 and 10%. If you need to constantly monitor and know the humidity level in your baby's room, you should choose a hygrometer with an accuracy of between 1 and 5%. Finally, there are other more specific uses, such as measuring the humidity in a cigar box or the case of a musical instrument, for example. In these cases, a high-precision hygrometer, whose margin of error is generally no more than 1%, is recommended. These are high-end, and therefore expensive, instruments.

#2 - Measurement range

Expressed as a percentage, the measurement range indicates the relative humidity level that the hygrometer can measure. While some instruments can operate over a measurement range between 20% and 80%, others offer an accuracy of 0 to 100%. This criterion is especially important if you use the hygrometer in extreme conditions.

#3 - Ease of use

The choice of hygrometer type usually determines its ease of use. Digital models, also called electric hygrometers, require no prior adjustment before they are turned on. In addition, they provide clear, detailed, and easy-to-read information on their digital or LCD displays. For this reason, many users prefer them to mechanical models. Indeed, the latter often require an initial calibration out of the box, to be repeated once a year. Despite the calibration guide provided with the product, this operation is not always simple for the average person. However, there are models of mechanical hygrometers that do not need calibration.

Wireless sensors

If you also want to measure the humidity level outside, you should know that there are digital hygrometers connected to additional sensors. You can install them on the terrace for example. These sensors contribute to the accuracy and richness of the measurements provided. They are of course wireless devices.

#4 - Design

Hygrometers are both functional and decorative objects that should enhance the interior space. They come in a wide variety of shapes and sizes. Their design also varies depending on the type of instrument. Digital hygrometers often have a flat square or rectangular shape and a stand that allows them to be placed on a flat surface. As for the mechanical models, they have a round shape with a thickness more or less important according to the price and the brand. They can have a foot that allows you to put them on a desk or another piece of furniture. Their manufacturing materials vary, but their dial and shell are very often made of metal (stainless steel, chrome steel, gold...).

#5 - Options available

If you are interested in digital hygrometers, be aware that they can offer interesting options depending on your needs. For example, you can opt for a model with sufficient memory and data logging function. They can provide you with the measurements of the last 24 hours. Others can analyze the variations of the measurements and indicate a trend for the next few hours. Still others are distinguished by their ergonomics, especially models equipped with backlighting and touch function.

Why and how to use a hygrometer?

The purchase of a hygrometer complements that of a humidifier, a mechanical ventilation system or an air dehumidifier. Indeed, it is important to make sure that the humidity rate of the ambient air remains within the standards, i.e. between 45 and 65% in a house.

To monitor the relative humidity in the house and ensure the health of the occupants

An atmosphere that is too dry or too humid can have consequences on health. If the air is too humid, the most fragile people are exposed to risks of allergy, asthma or other respiratory problems. Excessive humidity also encourages the growth of bacteria and dust mites.

On the other hand, if the humidity is too low, the occupants of a house can suffer from eye irritation or itching. Therefore, to be sure that the room humidity is within the standards, it is necessary to use a hygrometer.

To preserve materials

But this instrument is also used to preserve your home and certain objects that need to be kept away from humidity. Indeed, excessive humidity leads to the appearance of mold, the deterioration of wall paint or the degradation of certain materials such as wood.

Humid air is also the enemy of delicate objects such as musical instruments or cigars for example. For all these reasons, the use of a hygrometer can be essential.


Install the hygrometer so that you always have reliable measurements. You can put it in your bedroom, your baby's bedroom or in the living room. In any case, avoid certain locations. Do not place the instrument near a window, a humidifier or a heater, as this may distort the measurements. Also avoid placing it behind a curtain, because it will not be able to provide reliable measurements where air is not circulating.

The different types of hygrometers

In addition to special instruments such as dew point moisture meters or gravimetric moisture meters, three main types of moisture meters can be distinguished

Mechanical hygrometers

Also called analog hygrometers, mechanical hygrometers measure the hygrometry thanks to a material which expands or retracts according to the humidity level. This material then activates a needle which indicates the value on a dial with a number. There are mechanical hygrometers with hair and those equipped with a metal spring.

Sought after by collectors or lovers of decorative objects, analog hygrometers require prior calibration. Fortunately, this operation is facilitated by a guide provided. It should also be noted that the functionalities offered by this type of hygrometer are reduced, since only the percentage of humidity, the temperature and sometimes the comfort level are indicated on the 2-in-1 models.

Digital hygrometers


known as electric hygrometers, digital hygrometers measure the humidity level using electronic sensors equipped with an electric resistance. They work with electric batteries. Their first advantage is their ease of use: they require no adjustment or calibration

. In addition, they offer a wide range of information, such as trends and the latest measurements recorded.

Additional features can be provided, such as a mold alarm, clock, temperature or remote measurement using sensors placed in another location. Aesthetically, digital hygrometers are less attractive than their mechanical counterparts. Nevertheless, some models from major brands adopt a neat design, a mix of smooth surface and extra flat shape.

Capacitive hygrometers


their name suggests, these hygrometers are equipped with a capacitive humidity sensor. The principle is to measure the humidity with a metal oxide or polymer film that absorbs and measures the moisture. The value is then displayed on a digital screen as on a digital hygrometer.

Mainly intended for professionals who work on a construction site or for the maintenance of a building, capacitive hygrometers are very precise, but expensive. Their high accuracy means that they have only one function. However, they must be regularly maintained, including periodic replacement of their sensors. They also need to be calibrated before each use.

Mechanical or digital hygrometer?

Mechanical hygrometer

If you are looking for an instrument that is as functional as it is beautiful, and if the need for calibration does not bother you, you can consider buying a mechanical hygrometer. In addition to offering a very good level of precision, it is distinguished by its aestheticism which often exudes solidity, given that it is often made of metal.

If you have a weakness for old-fashioned styles, especially the needle display, the analog hygrometer will give you complete satisfaction. However, remember to choose a top-of-the-range model made of metal that will also decorate your interior.

Digital hygrometer

Do you need an instrument that is easy to use and quickly functional? Then you can opt for a digital hygrometer that can also be very accurate. Once you turn it on, it provides you with the humidity measurements and any other data you need quickly and without prior adjustment.

Another notable advantage is that this device does not require regular maintenance. And to help you find the perfect model, it comes in a variety of designs.


Beyond their different designs, analog and digital hygrometers have in common their ability to give reliable measurements of relative humidity. They are designed to cover various needs. Nevertheless, analog models are visually more attractive, while digital ones are easier to use.


Do a calibration before using your mechanical hygrometer.

Although most analog hygrometers are factory calibrated, it is best to calibrate your instrument before using it. Follow the instructions in the user's guide or help yourself to tutorials easily found on the Internet.

Choose the hygrometer according to your needs.


choice of your hygrometer should be based in part on your needs. If you want to have an idea of the ambient hygrometry, a basic model may be enough. But if you need to react to the slightest deviation, opt for a more powerful model that will generally be more expensive.

Open your windows to reduce or increase humidity.


the measurements indicate that the humidity level is too low or too high, start by opening your windows. The circulation of air in your house contributes to the balance of hygrometry.

Increase humidity with damp cloth.


the humidity is low and you don't have a humidifier yet, you can increase it by putting a damp cloth on the heater

, for example.

The condensation will help humidify the air in the room.

Put leafy plants in your home.

Another way to remedy low humidity in the house is to place leafy plants in the house. This is because plants "sweat" by allowing water to evaporate through their leaves. This evaporation increases the humidity level.


What is the best hygrometer?

The best hygrometer depends on your needs and your budget. Read our buying guide for the best products of the moment.

What is the price of a hygrometer?


analog hygrometer is sold between €10 and €30. Digital models can be priced up to €50 depending on their options. Professional hygrometers can cost up to €100 or more.

Do I need a more accurate hygrometer for my baby's room?



fragile, baby is more sensitive to too large differences in hygrometry. Also, you need to monitor more precisely the humidity level in your baby's room. So choose a model with better than average accuracy.

Does a hygrometer require maintenance?


hygrometer doesn't need any special maintenance. All you need to do is check the batteries in the case of a digital model, and perform periodic calibration if you have a mechanical model.

Are there single function hygrometers?

Most home hygrometers incorporate two functions, that of hygrometer and thermometer. Digital hygrometers may also include the clock function, while some mechanical models double as barometers.
