Omega’s HHAQ-106 hand-held psychrometer with enthalpy measures ambient temperature, relative humidity (RH), dew point and wet bulb temperatures, absolute humidity (mixing ratio) and enthalpy of vaporization. These measurements are typically made by three groups of users: Water damage restoration contractors, HVAC/R system installers and technicians and professionals charged with monitoring and maintaining the environment of facilities such as office buildings, greenhouses, food and equipment storage facilities, wineries, freezers, shipping containers, computer rooms, labs, libraries, museums and saunas. The dew point is the temperature below which the water vapour in a volume of air at a given constant barometric pressure will condense into liquid water at the same rate at which it evaporates. Condensed water is called dew when it forms on a solid surface. Another way to think of dew point is as an air saturation temperature associated with relative humidity (RH). A high RH value indicates that the dew point is close to the current ambient air temperature. At 100% RH, the dew point temperature is equal to the ambient temperature because the air is completely saturated with water.
