Best Hygrometer For Indoor Humidity

Sharing is caring!

There are several reasons why you might need a hygrometer. Various health issues are linked to poor indoor humidity levels. Exposure to low levels of humidity can also decrease the quality of sleep and your overall comfort.

There are many digital hygrometers out there, but it’s hard to know which ones are worth the price. So come along as we share our top picks for hygrometers used for indoor humidity.

Comparison Table Of The 8 Best Hygrometers For Indoor Humidity

What is a Hygrometer?          

A hygrometer is a tool that measures the level of humidity in an area. They are responsible for providing the correct values on the amount of moisture in the air in a particular location.

These devices are also known as humidity meters or humidity gauges, which measure the changes in temperature and pressure.

Indoor hygrometers are small devices that usually have a digital display from 0% to 99%.

Some of them have trend indicators for you to determine whether the humidity is getting high or low. They also show labels, such as dry, ok, and wet, for easier reading.

Most indoor hygrometers also come with temperature sensors to act as a thermometer. That’s because humidity relies on temperature, mass, pressure, and other metrics.

Is a Digital Hygrometer Better than an Analog?

Digital Vs Analog Concept, 3D Rendering

It depends. First, digital hygrometers use new technology. But analog sensors are still used to measure the humidity levels, and then the results are displayed digitally.

This means the design is more appealing for a modern hygrometer and can fit various home décor.

Another reason why a digital hygrometer is better than an analog hygrometer is that it also comes with a built-in thermometer.

Some have Wi-Fi connectivity, which lets you access these readings on your smartphone. It also includes storage for those who want to keep a tab of their records over time.

Digital humidity monitors or humidity gauges are more readable because of the large number of displays and sometimes a backlight function. They may also have indicators that let you know if the values presented are normal or not.

Because they’re more modern, digital hygrometers show more accurate readings of the level of humidity than some analog humidity monitors.

Unlike analog meters, they do not lose accuracy over time, but their batteries need to be replaced. They do not need to be calibrated because they are already set when you take them out of the box.

However, these additional features often mean a higher price. Most high-end models have an unreasonable price, but there are also available products that are just as reliable.

You must be willing to spend a little more because digital hygrometers are more efficient for indoor use than analog.

But the decision on whether to get an analog or digital hygrometer is still up to you. Consider how much you want to spend and the features you need.

Are There Different Types of Hygrometers?

Yes. There are many types of hygrometers, but these are the most common.

Digital Hygrometers

Digital hygro thermometer in laboratory

Digital hygrometers are the most common kind of hygrometers used at home and in offices because they allow you to easily monitor humidity levels with their huge screen display. They’re great if you have a wine cellar, cigars, cigar humidors, monitoring basements, preserving the quality of a musical instrument, etc. 

They work in two ways. First, some hygrometers use two metal plates that catch moisture between them for the device to calculate. This phenomenon is called capacitance.

The second one works through resistance, where a ceramic substance passes through the unit and exposes itself to the air. Changes in resistance levels are seen when the humidity levels change.

A digital and accurate hygrometer can also be classified into indoor and outdoor. They’re great for measuring relative humidity, temperature levels, and more. 

Dew Point Hygrometers

A dew point hygrometer is a handheld unit for checking the dew point of a liquid. This is best used for measuring only small quantities of moisture, so it’s not ideal for checking the humidity of a whole room.


A psychrometer is a kind of hygrometer that uses a wet bulb and a dry bulb at once. The dry bulb is exposed to the air to measure the temperature, while the wet bulb measures the temperature when the bulb is dipped in liquid.

Calculating the difference between the two will let you identify the relative humidity of the environment.

Chilled Mirror Hygrometers

This type of hygrometer is just like the dew point hygrometer but with enhanced precision. It uses a chilled mirror whose surface is used to calculate the levels of condensation.

Metal Paper Coil Hygrometers

The metal-paper coil hygrometer is an affordable measurement tool for humidity levels that includes a strip attached to a metal coil.

This strip absorbs moisture to check the changes in your environment, and later on, transforms its shape. A needle is used to get the humidity reading for the user.

Optical Hygrometer

An optical hygrometer uses a light detector and a light emitter. This important type of hygrometer measures these values through the water absorption levels in the air between the detector and the emitter.

Hair-Tension Hygrometers

This hygrometer is one of a kind because it uses human or animal hair to determine the changes in relative humidity. The hair is put under pressure, and it becomes longer or shorter depending on the moisture content changes in the surroundings.

Gravimetric Hygrometer

A gravimetric hygrometer is one of the most precise hygrometers out there that utilizes a sample of air’s mass instead of an equal amount of dry air.

Optical Hygrometer

Thermal hygrometers include built-in sensors for determining the humidity. It also uses the air’s thermal conductivity to determine the absolute levels of humidity rather than relative. 

What is the Most Comfortable Humidity Indoors?

The rising humidity rate level rising on a thermometer past 100 percent to tell you of danger or uncomfortable weather conditions in the hot summer heat

The ideal relative humidity that is both safe and comfortable is approximately 30%-50%. These percentage values refer to the amount of moisture that the areas contain.

Too much humidity won’t let you and other people and pets in the house properly regulate your internal temperatures. A humid room may feel warmer to you even if it’s the same temperature as another room that is less humid.

It can also cause sickness since humid areas promote mold growth, dust mites, and fungus, which can worsen asthma and allergic reactions.

Over time, the wooden parts of your home, like hardwood floors, may break down, swell, and warp. This is also why guitarists have hygrometers attached to their guitar cases. 

On the other hand, if there is little humidity in the room, your skin may feel colder and itchier. You are more likely to experience chapped lips and sore throat since your mucous membrane is drying. You’re also prone to wheezing, coughing, and breathing difficulties.

Its effects on your possessions can also be adverse. Parts of your home may crack, shrink, and develop molding.

Factors to Consider When Buying a Digital Hygrometer

Finding the best humidity monitors for indoor use can be an arduous activity. To help you choose which one suits your needs, consider the following factors.


ThermoPro TP50 accuracy

Accuracy is the first thing to look for when you’re buying a digital hygrometer. Accurate humidity sensors are key to successful results and readings.

If you’re monitoring an extremely sensitive place or items, like wines and musical instruments, you need one with a margin of ±1-2% RH. But if you’re using it to monitor comfort levels only, around ±2-3% RH is enough.

These ±% RH ratings determine the margin of error. Ask yourself if you need a precise device or if a standard, affordable one is enough.

Application Area

Where do you plan to place your digital wireless hygrometer? Some prefer using it indoors to monitor greenhouses, living rooms, baby rooms, and wine cellars. But others need to gather data about the weather, so they place it outdoors.

If you are not certain about the place of application, then it will be hard for you to choose the right wireless hygrometer. Some hygrometers have a humidity range of 16% to 99%, so you won’t be able to monitor sensitive places or items. 

Display and Ease of Use

If you are shopping for a digital wireless hygrometer for home use, choose one that’s easy to assemble. Most of these devices already come pre-calibrated out of the box.

Does the hygrometer have an LCD display with large digits? This is also important so that you can monitor the levels even from afar. It’s even better if it has a backlight function for maximum readability in low-light situations.

The digital hygrometer may also display trend indicators to let you know if the room is getting moist or dry. It should also have labels like dry, ok, and wet for your convenience.

The display and ease of use are necessary, especially for older people and those who have vision problems. Check for customer reviews about its user interface to get an idea of the quality of the product.

Power Source

Is the hygrometer battery operated or wired? This is another essential thing that many people tend to overlook. If you’re going for wired mechanical hygrometers, remember that you need to place them near a plug. It can also increase your electric bills.

But if you choose wireless connectivity, then check what type of battery it supports. A battery-operated hygrometer is also more common in the market. It lets you place it anywhere, whether it’s on top of a surface, hung on the wall, or stuck through a magnet.

We recommend using a rechargeable battery such as a lithium-ion AA battery.

Battery Life

ThermoPro TP50 battery

Once you know the type of battery it supports, make sure it has a long battery life. You don’t want your electrical hygrometer to stop working when you need it the most.

One way to save battery life is by making sure the backlight function can be turned off. Some digital humidity monitors automatically turn off their lights after ten seconds.

Additional Sensor Support

Are you going to monitor ideal conditions in several locations at once? If so, you will need a digital hygrometer to connect to various sensors in one system. The main hub has to be reliable, and the range of distance has to be wide.

Remote Alerts

Not everyone needs a digital hygrometer that lets you monitor the levels remotely through your smartphone. But if you do, make sure that the app is user-friendly and does not require additional costs for a subscription.

These devices are more expensive, but they can be worth the cost if it means you’ll be able to get alerts when the temperature and humidity go beyond normal. You can also customize the intervals for notifications and where you will get updates. Some offer email and SMS options too.

Some digital hygrometers let you store data for up to two years. You can even download and export them into a CSV or PDF file.

Take the time to discern whether you need all these additional features or not.


You don’t have to spend a lot of money on a high-quality indoor humidity monitor. Some models are cheaper than well-known brands but still offer accurate temperature and absolute humidity levels, a wide range, trend indicators, and multiple mounting options.
