A humidity test gives information about the amount of water vapor or moisture in your home.
Too little or too much humidity can lead to a variety of issues for your home and family.
To ensure that your home has the right level of humidity, more so during the months that have the windows closed, carry out some simple visual tests, or use your hydrometer to test the relative humidity of your home accurately. To test humidity in your indoor space, start by choosing between a mechanical or electronic hygrometer. While a mechanical one responds to your home’s humidity levels if left in one position out of drafts and sunlight, an electric hygrometer utilizes batteries. It has a liquid crystal display and a plastic case. Prepare your mechanical hygrometer for calibration by adjusting the pointer. An electronic one does not require this adjustment. Mix ¼ cup tap water and ½ cup table salt in a container until the salt dissolves. Put your mechanical hygrometer and your solution inside a plastic bag out of direct sunlight in an area void of drafts. Leave them in the sealed bag for 8 to 12 hours, then check your hygrometer’s dial to see if the pointer is at 75%. If not, take note of the variance between 75% and its reading. Then Adjust your hygrometer to 75% if it’s adjustable, using the knob or screw adjustment. You will need to follow your manufacturer’s instructions to use your electronic hygrometer. Check the setting on your hygrometer to ascertain the relative humidity of your home.
