Comparing the difference in temperature between wet and dry bulb thermometers has long been the most accurate method of calculating relative humidity.
The wet bulb thermometer comes complete with a length of cotton tubing which acts as a wick between the reservoir and the thermometer and covers the humidity range between 40% to 100%.
Very good product, fast delivery, thank you very much
