We look at the best hygrometer currently on the market, and offer you reviews, advice, tips and information on choosing the most accurate hygrometer for your home.
We’ve talked about having the best level of humidity but how can you find out how humid or dry the air in your home is?
By using the best hygrometer thermometer, also known as a digital humidity meter, you can accurately measure the moisture level and temperature in a room. This helps you decide whether you need a humidifier or dehumidifier in your home..
Regardless of where you live, whether it’s in a tropical region or somewhere cold where you constantly use heating, your home’s air quality will impact your comfort and health.
It’s important to know the humidity level in your home. If the humidity is too high, you’ll want to use a dehumidifier. If the humidity is too low, you’ll want to add moisture to the air via a humidifier.
The best way to check the humidity level in your home is by measuring it using a hygrometer. Make sure you have an understanding of optimal humidity levels- this isn’t just something people in the tropics need to know. If you’ve ever suffered from a dry cough in the middle of winter, it’s probably from a low humidity level.
I’ve written this product review article so you can choose the best digital hygrometer for your home, but also so that you can learn more about humidity and how a hygrometer can help you.
Here’s a table showing you the best hygrometers I’ve researched and reviewed:
What is a hygrometer?
A hygrometer measures the level of moisture in the air and gives you a measurement as a percentage. It tells you roughly how much moisture is in the room. This can help you decide whether you need to switch on your humidifier or dehumidifier.
Hygrometers are typically used by meteorologists and also in any industry where it’s important to know moisture levels (such as when you’re painting, using a greenhouse or working with chemicals).
But hygrometers are also used in homes and offices- they help people adjust the moisture levels in their homes. This is important for comfort and to prevent problems such as mold, which can occur in small, dark spaces such as bathrooms and basements.
Other uses for hygrometers include preserving cigars, using incubators to hatch eggs, in saunas and hot rooms and keeping your wooden musical instruments in good condition.
Which Is The Best Digital Hygrometer To Buy?
In summary, our best hygrometers (in no particular order) are:
AcuRite 00613A1 Indoor Humidity Monitor

If you need humidity and temperature readings for different areas in your home, then the Ambient Weather WS-10 will allow you to do this.
The Ambient Weather WS-10 is a great option for those looking for a digital thermo hygrometer. Inside the main console, there is an indoor thermometer/hygrometer with an additional 3 thermo/hygrometer sensors displaying information at the same time. The system can use up to 8 sensors- only 3 sensors are included in the price when purchasing the Ambient Weather WS-10, however additional sensors can be purchased.
If you’re looking to buy an outdoor thermometer hygrometer, you’ll be happy to know that the Ambient Weather WS-10 can be used outside.
There is a display on the actual sensors as well on the main console- so you can check your main console to obtain the readings of the additional sensors.
Even though the information can only be displayed for up to 4 sensors, if you have more than 4 sensors there is a scroll through mode available. The display unit automatically scrolls through up to 8 of the sensors without you needing to do anything.
The console display shows you the temperature and humidity, with both a minimum and maximum value.
What we love about the Ambient Weather WS-10 is that you can set a minimum and maximum humidity level, and when the room reaches this level, the display console has an audible and visual alarm to let you know. This will help you know when you need to adjust the humidity and temperature in a room. Note that this feature is not possible for sensors located outside.
- Being able to measure multiple temperature and humidity levels at the same time both indoors and outdoors
- An excellent choice for large homes with many rooms
- Audio and visual alarms to indicate when a temperature/humidity level has been reached
- The alarm feature is only possible in indoor locations
- Can be costly when adding up the additional sensors and batteries required
- Is more complex to set up initially
The Extech is a humidity meter which measures humidity levels, temperature and, unlike most other digital hygrometers, it measures the dew point. This is the point at which condensation occurs.
Its large design makes it easy to view the readings, and it can be mounted on a wall but also includes a stand for use on a desk.
The Extech is another great option for those looking for a digital thermo hygrometer that can measure both humidity and temperature.
The digital hygrometer includes an audio and visual alarm so that you can set a humidity level or temperature and the unit will let you know once the set level has been reached. You can set new levels by pressing the reset button at the bottom of the unit.
One of the great things about the Extech thermo hygrometer is that it includes a remote probe that can either be clipped onto the unit or it can be extended using the included 18 inch cable. This means that you can use the Extech for readings behind walls and in hard to reach places.
For digital hygrometer calibration, the Extech has an optional calibration kit or it can be calibrated using the rear adjustment pot that has a minimum and maximum function as well as a reset function. If you want the most accurate digital hygrometer on the market, the Extech is worth considering. It is a high accuracy hygrometer.
If you are looking for the best hygrometer, the Extech comes with an optional NIST Traceable Certification. It meets ISO and other national standards for product accuracy.

The Meade Instruments digital hygrometer replaces the now-discontinued Honeywell TM005-X. This is essentially the same digital hygrometer but upgraded and with a new brand name.
The Meade digital hygrometer can be used indoor or outdoor to measure the temperature and humidity levels. Up to 3 additional sensors can be purchased.
The main unit can read the data from the other 3 sensors, and the extra sensors also have a display so that you don’t need to walk back to the main unit to check the readings. Data displayed includes minimum and maximum levels as well as high and low temperatures.
You can choose to have your temperatures displayed in either Fahrenheit or Celsius.
The main unit has a very accurate reading however using the sensor outside does not give as accurate a reading. Readings when humidity levels are below 20% are also not as accurate. If you are looking for the most accurate hygrometer, then we wouldn’t recommend the Meade digital hygrometer for outdoor use.
Furthermore, the sensors are not waterproof so if you use them outside, you will need to be careful of where you place them.
Although the Meade Instruments digital hygrometer is not a stylish design, it is quite large making it easy to read and use.
- Easy to read and use
- Main unit can read up to 3 additional sensors
- Great price
- Additional sensors are not waterproof
- Best used as an indoor thermometer hygrometer
- Not the most accurate hygrometer
Why should I use a digital hygrometer?
Types of hygrometers
The two main types of hygrometers are digital hygrometers and analog hygrometers. Digital hygrometers are the most commonly used in households, so these are the ones I’ve reviewed in this post.
How To Choose The Best Hygrometer
How can you find the best hygrometer for you home?
When I was researching and reviewing digital hygrometers currently on the market, I considered the following:
Ease of use
When you read about digital hygrometers, many consumers talk about the accuracy of the measurements. This is one of the biggest pitfalls of a digital hygrometer- you will always find a difference in measurement from one digital hygrometer to the next. There are always slight variances, and it’s very difficult to get a reading that is 100% accurate.
If you keep this in mind when choosing a digital hygrometer, you won’t be disappointed. For each hygrometer I’ve reviewed, I’ve mentioned how accurate the hygrometer is. Some are better at accuracy than others.
When choosing the best digital hygrometer, think about the space where you will be using the hygrometer and how many rooms you’d like to measure. If you need it for multiple rooms, particularly if you have a large home or live in a tropical environment, you’d need to choose a digital hygrometer that has more than one digital sensor and can perform multiple readings.
Why Should I Buy A Hygrometer?
Most humidifiers now come with a built in humidistat, which is essentially a type of hygrometer. Humidifiers use the humidistat to determine whether the desired humidity level has been reached- and once it reaches this level, the machine usually shuts off.
However, humidistats are not always accurate, and may only measure the humidity level in the surrounding area of the home. To get a more accurate reading of the humidity level in an entire room, you’d be better off buying the most accurate hygrometer.
A hygrometer is a humidity measuring device that measures how much water vapor is present in the air. It displays the humidity level as a percentage. This helps you decide whether you need to humidify or dehumidify a room or your entire home, depending on your personal needs.
For example, an asthmatic or person with other respiratory problems would want to prevent dryness in the air, which can irritate the respiratory system. By using a digital hygrometer, an asthmatic person can keep an eye on moisture levels and when they drop below a certain point, they can switch on their humidifier.
A digital hygrometer can also help you measure how humid a room is so that you can adjust the humidity levels and prevent mold and bacteria build up. Some areas of the home are more prone to humidity such as bathrooms and laundries. This can lead to paint and furniture damage as well as respiratory issues.
If you are looking for a digital thermo hygrometer, you won’t have trouble finding one that can measure both temperature and humidity levels.
If you are budget-conscious or someone who prefers to reduce energy consumption for environmental reasons, using a digital hygrometer can help you with this. Rather than leaving a humidifier to run for hours, a digital hygrometer can let you know when your desired humidity level has been reached. Some digital hygrometers have an alarm that will let you know. You can then switch on or off your humidifier or dehumidifier, potentially saving you money on your energy bills.
