Hair hygrometer 303700
Hygrometers are used to measure relative humidity and are based on the moisture-dependent change in length of hair and synthetic fibers.
Hair hygrometers are preferred for outdoor measurements where the hygrometer is regenerated daily due to the high nighttime humidity. The specially treated human hair is virtually temperature insensitive (temperature range -35 ° C to + 65 ° C) and reacts quickly to any change in humidity.
Hygrometers with synthetic fibers are particularly suitable for moisture measurements in production and storage rooms, in living rooms and offices. They are virtually maintenance-free, have a linear graduation and also have a very low hysteresis. The highest measuring accuracy is achieved by fiber hygrometers in a temperature range from 0° C - 40° C.
Hygrometer 303700 takes measures through Hair and it is manufactured by silver colored plastic.
