Explanation of calibration curves :
relHum: This shows the relative air humidity in %RH (relative humidity) and the
temperature in the selected unit (°C or °F).
absHum: This shows the absolute air humidity in g/m³ (grams of water per cubic
meter of air) and the temperature in the selected unit (°C or °F).
Dew Point: This shows the dew point and the temperature in the selected unit (°C
or °F).
EMC Wood: This shows the equilibrium moisture content of wood (for the timber
stored under these conditions) in % moisture cont. of wood and the temperature in
the selected unit (°C or °F).
