There are a lot of places to buy a sling psychrometer. Any company which sells scientific equipment should have them, or one could buy it from Amazon or Bacharach.
Distilled water is used with a sling psychrometer because it ensures that there are no impurities or minerals that could affect the accuracy of the instrument. Impurities in water could lead to inaccurate readings when measuring humidity levels. Using distilled water helps maintain the sensitivity and reliability of the psychrometer.
To use a psychrometer, follow these steps: Wet the wick or sling of the psychrometer with distilled water. Swing the psychrometer in the air for a few minutes to allow evaporation to take place. Read the dry-bulb and wet-bulb temperatures from the psychrometer. Use these readings to calculate the relative humidity using a psychrometric chart or formula.
Relative humidity
The sling psychrometer was invented in 1887 by Adolph Richard Assmann, a German meteorologist. It is a simple instrument used to measure the relative humidity of the air.
A sling psychrometer (which is a hygrometer) measures the moisture content of the atmosphere surrounding it. It is called a sling psychrometer because it is whirled around in the air until a constant value/reading is obtained from the wet-bulb thermometer.
The unit for a sling psychrometer is degrees Celsius (°C) for measuring air temperature and percentage (%) for measuring relative humidity.

A sling psychrometer typically contains two thermometers: a dry bulb thermometer and a wet bulb thermometer. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer measures the wet bulb temperature after being moistened with water. These readings are used to calculate the relative humidity of the air.
One of the better ways would be to use a sling psychrometer.

A sling psychrometer measures relative humidity by comparing the readings of two thermometers, one dry and one wet. It works on the principle that the rate of evaporation is influenced by the humidity of the air.
The temperature and dewpoint of the air (degrees), eventually indicating the relative humidity (percent). Both are dimensionless numbers ... they have no units.
Like in a Hygrometer to measure humidity you use percentage (%)
