10.2 Dew point accuracy
The HF6 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 20 ˚C, a frost point value of -25 ˚C is measured with an accuracy of
± 0.5 ˚C or better.
