Hygrometer, an instrument used to measure the moisture rate of dehumidification in the air. In the history of the development of hygrometers, a Swiss physicist and geologist by the name of Horace Benedict de Saussure invented the first-ever hygrometer using a human hair. There are some hygrometers that measure the change in electrical resistance using a piece of Lithium Chloride, and other semiconductor instruments that affect relative humidity.
Inside your home home, you must have a hygrometer that is user-friendly. How will you know if your hygrometer is easy to use or not? First, your hygrometer must be easy to read. The accurate humidity in house environment should be reflected on its display. Some hygrometers are called electronic hygrometers. These are made with LCD for your reading convenience. The cost of this electronic hygrometers range from $15 to $60.
Second, your chosen hygrometer must perfectly provide users accurate humidity readings for optimal humidity control. The term for this is accurate calibration because all hygrometers must be properly calibrated. Unfortunately, some hygrometers in the market today lack this salient hygrometer characteristic which are called drift. Drift means that a hygrometer cannot sustain its accuracy over the years. Because of this, you must re-calibrate your device at least once a year. This must be especially applied to the mechanical types of hygrometers.
On the other hand, humidity in house refers to the amount of water vapor released in the air within your house which can affect indoor air quality. Humidity in house varies on a daily basis year after year. During winter months, moisture due to your daily activities leads to high levels of humidity. To control relative humidity in your house, turn down your humidstat or use a warm mist humidifier.
Hygrometers come in different styles to suit your needs. A hygrometer can be a digital or analog type, and for home use or industrial purposes. In availing one, you should look at the scale of the hygrometer. If you are reading scales in Celsius, buy one with a Celsius scale otherwise, buy one with a Fahrenheit scale.
Next, check the graduation measurements on the hygrometer. Be sure that it has large numbers for convenient measurement readings.
Third, it must be easy to use that it doesn’t require any technical expertise to operate. Furthermore, it must have a warranty so that you can have a peace of mind in case it immediately breaks down.
The invention of a hygrometer really helps however, users must have an adequate understanding of the hygrometer especially on how to care of it properly to make it last for a lifetime.
