What is a Digital Hygrometer?

A hygrometer is a device that measures relative humidity. Many models come with indoor and outdoor temperature sensors that are also handy. If you have a humidifier and need to know when humidity levels are low enough to begin using one effectively, you may wish to invest in a hygrometer. This can be especially helpful for portable models of home humidifiers that are put away during the "cooling season" in the summer months. Once fall begins to turn to winter, you can monitor the hygrometer day to day to see where the humidity levels are at in your home. Once the moisture level become low enough, you can break out your portable humidifiers and put them to work. The hygrometer is also a good way to gauge whether your humidifiers are set properly. If there is too much moisture in the air, you can adjust the settings on your air humidifier and keep the moisture level at the proper levels.
