Relative humidity (RH) is the term used to describe the amount of moisture present in the air. A tool used to accurately measure humidity is called a hygrometer. There are different kinds of hygrometers available in the marketplace and they all do basically the same thing – calculate humidity levels.
Before we take a closer look at our pick of the top 5 humidity meters for indoors, let’s find out exactly what they do.
When you use a hygrometer you are looking at whether or not your home or workspace has a comfortable and safe level of humidity. For example, the ideal ‘zone’ is between 30 and 50 percent RH.
When humidity is too high, you may notice a musty smell in the air. Mold and mildew may form which can cause allergic reactions. When the humidity is too low, the air is dry, which may cause your skin to itch and crack.
The best way to regulate moisture in the air in your living or work environment is with a humidifier or a dehumidifier. Make sure that you check out our other articles on filterless humidifiers, furnace humidifiers as well as general dehumidifier information.
The Different Types of Hygrometers
There are two different types of hygrometers available for purchase for home use. They are analog or digital.
The analog-style typically features an antique or rustic design. As for the inner workings, analog hygrometers are not considered as accurate as digital models. As a result, analog hygrometers require regular recalibrating.
Digital hygrometers are inexpensive to buy and are generally considered to be much more accurate than analog models. This is one reason why digital hygrometers do not require recalibration. Manufacturers of digital devices have also incorporated several additional features making one of these a multi-purpose measuring tool.

For instruments intended to measure relative humidity, hygrometers can have several additional useful features. Digital models generally contain more than analog ones. The average analog indoor humidity meter will have a more intricate outer design and less functionality. In other words, if you are looking for something that can provide a lot of data, the digital ones are your best bet.
Digital hygrometers not only record and display more information, but they also come in various shapes and sizes. Because of this, you will want to make sure you match the right size unit for the size of the space you wish to monitor the humidity of. For example, there are digital models made specifically for greenhouses. However, most are designed for home use.
Plus, the digital indoor humidity gauge style is considered easier to use and more convenient due to size. Some have a magnetic back so placement can be easy in tight spots. Others have built-in stands. Other features include well-lit screens with large numbers. Some feature additional readings such as indoor and/or outdoor temperatures.
Here are our picks for the top 5 best indoor hygrometer choices:
ThermoPro TP50 Hygrometer Thermometer
Powered by a single AAA battery (included) this device will give you a lot of information about the moisture content in your home. In addition to humidity and temperature readings, the air conditions are rated in three categories (dry, comfort, wet) to give you a quick reference.
The indoor temperature and humidity gauge also display high and low records for both humidity and temperature. It features a tabletop or magnetic mounting design and a 3-year warranty (if you register your unit).

AcuRite 01080M Temperature & Humidity Monitor
This indoor thermometer hygrometer continuously measures conditions every ten seconds and is accurate to +/-0.5 degrees F and +/-2% relative humidity (RH) according to the manufacturer, but also has a built-in manual calibration feature. Add to this the programmable alarm to indicate high or low humidity and a 24-hour record of the high or low readings and you see that this is a multipurpose device.
The meters are easy to read and tell you with just a glance the conditions of the area you are monitoring.

Govee Indoor Hygrometer Thermometer
This is a great looking humidity monitor with a jumbo LCD display. Bluetooth connectivity feeds data related to temperature and humidity to an app on your phone from as far away as 260 feet / 80m.
It also has smart notifications that will alert you when temperature or humidity exceeds a preset range. This makes it ideal for monitoring conditions in sensitive areas like wine cellars or greenhouses.
This unit has built-in data storage plus the option to export the last 2 months of data to a CSV file.
This hygrometer requires 2 AAA batteries to operate, which are included.

Kalawen Wireless Digital Indoor Outdoor Weather Station
The Kalawen Weather Station is actually designed for indoor as well as outdoor use, but we thought it deserved to be on our list of the best indoor hygrometers for quite a few reasons.
This unit comes with one wireless remote sensor and space to add up to three in total (others are sold separately). The remote sensors have a range of approx. 200ft / 60m, so you can place them at various locations of interest around your home or property.
The display is very large at about 8in x 5in, and has large characters that can be read from a distance, making it super-easy for people that don’t have the best eyesight to read. Rather than the traditional grey display, this unit has a color display with graphical icons to quickly show you what is happening at a glance.
As you would expect, it can display either Fahrenheit or Celsius temperature readings. It also provides hygrometer, pressure, time and alarm information.

Ambient Weather WS-110 Wireless Weather Station
The interesting design feature with this accurate hygrometer for home use is that the backlight color of the display changes with the temperature. This makes knowing the conditions within your monitoring zone just a bit easier than having to read an actual temperature number. Plus, the large display has you covered by providing the date, time, indoor/outdoor temperatures, humidity, and dew point readings.
This unit is also designed to accommodate multiple additional sensors. If that’s not enough, barometric pressure, daily highs/lows and a graph will tell you even more information.
If you are looking for an all-in-one indoor thermometer and humidity gauge, this would be it.

The best indoor hygrometer is the one that provides you with the data you require in keeping your home or workspace comfortable. Different models offer different levels and amounts of this kind of information with digital styles offering more data.
The main reason for having an indoor hygrometer is to monitor the moisture content in the air you are breathing. When it gets too dry or too wet, you are at the risk of several health-related issues. They range from allergic reactions and skin irritations to the formation of mold.
When the humidity registers in the range where it is too low or too high, the moisture content can be regulated to bring it back to a safe and comfortable level. The best way to control the humidity in a given area is with the use of a humidifier or dehumidifier.
Combining the use of a humidifier or a dehumidifier with an indoor hygrometer is the perfect solution. That’s because you should be able to monitor the humidity level on a regular basis. When it is in need of regulating, you can address that issue immediately.
