Figure 7.1

  • As found calibration using a precision dew point standard with an accuracy of ±0.1 °C DP.
  • Dew point hygrometer sample tube installed in the humidity generator test chamber.
  • Additional temperature measurement for as found temperature comparison.
  • Record as found calibration at humidity test points from 10 %RH to +90 %RH.


Insert the Temp Probe.
