Hair Outdoor Hygrometer Model 11101
For outdoor measurements and in high humidity
4" diameter Hair hygrometers are specially used for outdoor
measurements (in shaded or protected areas) or in places where it is very humid.
The specially treated human hair of the
Hair-hygrometer 11101 is temperature-insensitive
(temperature range -35 °C to +65 °C) and reacts
quickly to any change of humidity.
In low humidity environments, real hair hygrometers will require some maintenance. Please see the Care and Maintenance document in the documents tab.
