Polymeter temperature, absolute and relative humidity, pressure, dew point and saturation deficit.


Product Description

Polymeter temperature, absolute and relative humidity, pressure, dew point and saturation deficit.
This Hair Polymeter is a hygrometer thermometer for measuring and calculation of air temperature in Fahrenheit and Celsius, absolute and relative humidity of air, saturation vapor pressure, vapor pressure, dew point and saturation deficit.

Hair hygrometers are specially used for outdoor measurements or in places where it is very humid. The specially treated human hair of the Hair-hygrometer 111.01 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.
