If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. Moisture content measures by g/1kg dry air. Note that the Mollier diagram is actually identical to the psychrometric chart but just mirrored and turned 90 degrees.

Relative humidity and dry-bulb temperature Wet-bulb temperature and dry-bulb temperature or Dew-point temperature and dry-bulb temperature. (Note: absolute temp = Celcius + 273.15 approx.) The wet bulb temperature is always lower than the dry bulb temperature but will be identical with 100% relative humidity (the air is at the saturation line). Humidity Monitor is a very useful, simple app which helps people get the current outdoor relative humidity (RH), absolute humidity (AH), specific humidity (SH), dry bulb temperature (DBT), wet bulb. Relative Humidity is measured using a device called a sling psychrometer.This consists of 2 side by side conventional thermometers, one of which (the wet bulb thermometer) has a wetted wick placed at the bottom, the other (the dry bulb thermometer) has no wetted wick. We are > looking for a formula to calculate a RH setpoint to use for control. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air.
