Relative humidity is the term used to describe the moisture content of the air in our homes and outdoors. If you are seeking an affordable and easy way to monitor the relative humidity in your home, a digital hygrometer will do the job for you.
There are some great and well-priced digital hygrometer options on the market. But before we look into the best digital hygrometers that are available, let’s have a quick look at why you may want to monitor the humidity in and around your home.
Why Controlling Humidity Is Important
Dry or wet conditions can have an impact on our homes and its contents. Humidity can cause a great deal of damage. When the relative humidity is too low it can cause wood to crack. When it is too high, it can create mold, mildew and not only damage structural integrity, it can make us sick.
In addition to this, and possibly more importantly, there are many health conditions that can be triggered but too much or too little humidity.
A hygrometer helps you to monitor and keep the humidity in the proper zone. A hygrometer does not actually adjust the relative humidity. A hygrometer gives you a means of measuring the humidity level in your home. You can then use a good humidifier or dehumidifier in order to correct the relative humidity when required.
The Different Types of Hygrometers
There are several different types of hygrometers in the market. They fall under two basic categories. These are analog or digital hygrometers. You can also get indoor and outdoor hygrometer versions of each type.
In addition, hygrometers are battery-operated or electronic using power from your home electrical system. The number of features on each style varies with price determining the actual number of features and total functionality of an individual unit.
Generally speaking, once you set up your hygrometer, there is little in the way of maintenance. The exception being models that require batteries and outdoor models that may require replacement after years of exposure to the elements.
Why You Would Use A Hygrometer
Essentially, having the ability to monitor the relative humidity in your home allows you to keep your living space comfortable. Much like a thermometer permits you to monitor and control temperature, a hygrometer allows you to closely monitor humidity and adjust it if required.
