Mark other points on the scale by noting readings on a wet and dry bulb hygrometer or according to the relative humidity reported by a radio or TV station. When the pointer has moved as far as it can, mark this point 100 on the scale, because the air in the bucket will be 100% saturated. To calibrate the scale, place the hair hygrometer above warm water in a bucket and cover with a wet towel.
