118.01 | Polymeter

The polymeter is a hygrometer thermometer for measuring and calculation of air temperature, absolute and relative humidity of air, saturation vapour pressure, vapour pressure, dew point and saturation deficit.
For outdoor measurements and in high humidity hair hygrometer are preferable. The specially treated human hair of the Fischer polymeter 118.01 is insensitive to temperature (temperature range -35 to +65 °C) and responds quickly to changes in humidity.

• Measurement range 0 to 100 % relative humidity; -35 to +55 °C
• Measurement accuracy ± 3 % RH (20...100%); ± 2 K
• scale graduation 1 % r.F.; 1 °C
