Introduction
CongratulationsonyourpurchaseoftheModelIRT600DewPointTemperatureDetector!The
IRT600iscapableofdisplayingAirTemperature(AT),SurfaceTemperature(ST),Relative
Humidity(RH),andDewPointTemperature(DP)andcananalyzethepotentialformildew.The
LEDlampabovetheLCDdisplaychangescolortoindicatethe potentialformildew:green(no
mildew),yelloworamber(lowtomoderateprobabilityofmildew),andred(highprobabilityof
mildew).
TheIRT600measuresSurfaceTemperatureusinganinfrared(IR)sensorandincludesdualred
