Top 5 Best Indoor Hygrometer Options

Best Indoor Hygrometer Options
An indoor hygrometer is the most reliable instrument to measure humidity in your home.

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.

Design Features

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, they 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:

In Conclusion

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.
