Precision Hair Hygrometer

The Precision Hair Hygrometer measures the relative air humidity and is ideal for experiments based on weather conditions. Contained in attractive round plastic housing, a synthetic hair serves as the internal measuring element. The specially treated hair exhibits an almost inertia-free response to changes in humidity making this a highly effective piece of apparatus for weather measurements. The Hydrometer is fully wall-mountable for constant measurements air moisture.
