trodeks’s HHAQ-106 handheldpsychrometer with enthalpy canmeasure any environment’s ambienttemperature, relative humidity (RH),dew point and wet bulb temperatures,absolute humidity (mixing ratio) andenthalpy of vaporization. Thesemeasurements are typically made bythree groups of users: Water damagerestoration contractors, HVAC/Rsystem installers and technicians andprofessionals charged with monitoringand maintaining the environmentof facilities such as office buildings,greenhouses, food and equipmentstorage facilities, wineries, freezers,shipping containers, computer rooms,labs, libraries, museums and saunas.

The dew point is the temperature belowwhich the water vapor in a volumeof air at a given constant barometricpressure will condense into liquid waterat the same rate at which it evaporates.Condensed water is called dew whenit forms on a solid surface. Anotherway to think of dew point is as an airsaturation temperature associated withrelative humidity (RH). A high RH valueindicates that the dew point is close tothe current ambient air temperature.At 100% RH, the dew point temperatureis equal to the ambient temperaturebecause the air is completelysaturated with water. The wet bulbtemperature is the temperature thata volume of air would have if it werecooled to saturation (100% RH) by theevaporation of water into it, with thelatent heat coming from the volumeof air. It is the lowest temperature thatcan be reached under current ambientconditions by the evaporation of wateronly. The wet bulb temperature isthe temperature you feel when yourskin is wet and exposed to movingair as opposed to the actual airtemperature—the dry bulb temperature.An environment’s absolute humiditylevel (or mixing ratio) can be measuredand expressed in units of grains perpound (GPP) or g/kg. GPP is a moreuseful moisture metric than RH to waterdamage remediators. Using RH alone,a remediator might unknowinglyintroduce moist air—with a low RH but ahigh GPP—during a job’s drying phase.

The sixth environmental parameter thatthe HHAQ-106 can measure is enthalpy.Enthalpy is a measure of the amountof energy needed to change the stateof a substance from a solid to a liquidor from a liquid to a gas. The mostcommon application for theHHAQ-106 enthalpy-calculatingalgorithm is measuring the enthalpy ofvaporization of air in an HVAC/Rsystem duct.
