1990) model considers a coil to either be fully dry or fully wet depending on whether an equivalent coil surface temperature is greater than or less than the air inlet dewpoint temperature.
The first approach includes analysis of a gas on gas chromatograph and calculation of hydrocarbon dewpoint envelope (hydrocarbon dewpoint temperatures at different pressures) using some equation of state and characterization method.
On the psychrometric chart, this process is represented by a horizontal movement along a constant humidity ratio, dewpoint temperature, or vapor pressure line (ASHRAE 2001).
In other words, it is important to know whether very hot and humid conditions are likely to occur and to persist, but forecasting precise air or dewpoint temperatures is less consequential.
The dewpoint temperature is a measure of the water content in the drying air.

The Elcometer 319 Dewmeter measures relative humidity (RH %), air temperature (Ta[degrees]C/[degrees]F) and surface temperature (Ts [degrees]C/[degrees]F)and calculates the dewpoint temperature (Td [degrees]C/[degrees]F) and the difference between the surface temperature and the dewpoint temperature (T[degrees]C/[degrees]F).
