What are the parts of a sling psychrometer?

A sling psychrometer is an instrument that measures the relative humidity and dew point in an area. A sling psychrometer has two thermometers: a wet bulb and a dry bulb. The wet bulb has a cotton wick over the bulb of the thermometer, which is moistened with room temperature water.

How do you make a sling psychrometer?


  1. Moisten a double layer of gauze with water.
  2. Use the rubber band to cover the bulb of one of the thermometers with the gauze.
  3. Secure the thermometer with gauze on one side of the plastic bottle and the other thermometer to the opposite side, using multiple pieces of strapping tape.

What is required for a sling psychrometer?

A sling psychrometer holds a wet-bulb thermometer and a dry-bulb thermometer.

What does a sling psychrometer measure how is it composed?

A sling psychrometer is a simple meteorological instrument used to measure the relative humidity of the air. It consists of two thermometers on a structure that can be whirled in the air. The wet-bulb thermometer has an absorbent cover that is soaked in water before using the instrument.

What is use of psychrometer?

A psychrometer measures the relative humidity in the atmosphere through the use of two thermometers: a dry bulb thermometer, is used to measure the temperature by being exposed to the air. a wet bulb thermometer, measures temperature by having the bulb dipped in a liquid.

How is a sling psychrometer used?

A sling psychrometer can be used to find relative humidity, which is expressed as a percentage. It is computed by multiplying the amount of moisture in the air at a given temperature, dividing by the maxi- mum amount of moisture the air could contain at that same temperature, and then multiplying the quotient by 100.

What is a sling psychrometer used for?

Why does the hair shorten when humidity decreases?

Human hair absorbs moisture, lengthening up to 3 percent in humid weather. As the humidity changes, the lengthening or shrinking of the hair strands causes the hygrometer to display the current relative humidity.
