PR-125 HAIR HYGROMETER

A hygrometer is an instrument used for measuring the moisture content in the atmosphere.

The hair tension hygrometer uses a human or animal hair under tension. The length of the hair changes with humidity and the length change may be magnified by a mechanism and/or indicated on a dial or a scale.

Our device measures the relative humidity in air 0-100x 1% r.h.

It is a circular dial type hygrometer with a scale and is enclosed in a metal case.
