10.2 Dew point accuracy
The HF3 can be configured to calculate either the dew point or frost point based on the measurement of
relative humidity and temperature. The accuracy of this conversion varies, depending on the humidity and
temperature conditions as shown in the graph below:
Example: at a temperature of 1
0 ˚C, a dew point value of 0 ˚C is measured with an accuracy of
± 1.0 ˚C or better.
