Hair Hygrometer

How do you use a hygrometer?
To make and use a hygrometer, an instrument for measuring the level of humidity in the air. Changes in humidity are an important part of daily weather. In this science fair project you will build a hydrometer, an instrument used to measure the humidity level in the air. Your hygrometer will use strands of human hair as its sensing element.
What is a hair hygrometer used for?
The tool we use to measure humidity in this activity is called the hair hygrometer. In fact, the 1783 invention proved to be so reliable that it was not replaced by an electrical instrument until the 1960s. Create and use tools that measure relative humidity. What is humidity? Why is hair affected by humidity?
What is a hair tension dial hygrometer?
A hair tension dial hygrometer with a nonlinear scale. A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much water vapor it contains.
What is the length variation of a hair hygrometer?
The length variation of a properly treated hair is 2%–2.5% when the humidity changes from 0%–100%. The hair hygrometer is considered to be a satisfactory instrument in situations where extreme and very low humidities are seldom or never found.
