Introduction

CongratulationsonyourpurchaseoftheModelIRT600DewPointTemperatureDetector!The

IRT600iscapableofdisplayingAirTemperature(AT),SurfaceTemperature(ST),Relative

Humidity(RH),andDewPointTemperature(DP)andcananalyzethepotentialformildew.The

LEDlampabovetheLCDdisplaychangescolortoindicatethepotentialformildew:green(no

mildew),yelloworamber(lowtomoderateprobabilityofmildew),andred(highprobabilityof

mildew).



TheIRT600measuresSurfaceTemperatureusinganinfrared(IR)sensorandincludesdualred

laserpointersforimprovedtargeting.TheIRsensorhasa12:1DistancetoSpotratio.Thismeans

thatatarget30cmawayfromthemeterhasaspotdiameterof1.25cm,atarget45cmawayhas

aspotdiameterof3.75cm,andsoon.Theclosertothetarget,thesmallerthespotsizeandthe

furtheraway,thelargerthespotsize(verymuchlikeaflashlightbeambehaveswithregardto

distance‐to‐spotratio).



TheAirTemperatureandRelativeHumidityaremeasuredbytheinternalsensorsatthetopof

themeter.DewPointTemperatureiscalculatedusingAirTemperatureandRelativeHumidity

measurements.MildewanalysisisbasedoncalculationsmadefromAirTemperature,Surface

Temperature,DewPointTemperature,andRelativeHumidityvalues.



Thismeterisshippedfullytestedandcalibratedand,withproperuse,willprovideyearsof

reliableservice.Pleasevisitthewebsitewww.extech.comforthelatestversionofthisUser

Guide,CustomerSupport,andinformationonotherproductsofferedbyExtechInstrumentsand

FLIRSystems.

Safety



Useextremecautionwhenthelaserpointerbeamison

Donotpointthebeamtowardanyone’seyeorallowthe

beamtostriketheeyefromareflectivesurface.

Donotusethelasernearexplosivegasesorineither

potentiallyexplosiveareas.

Donotcleanthelaserwithanycorrosiveacidsorliquids.

Useanappropriate(9V)batterytopowerthemeter.

Operation

PoweringtheMeter

PressthetriggeroncetopowerthemeterONorOFF.



TurntheBacklightOn/Off

Pressthebacklight/laserbuttontoturnthebacklightonoroff.



SelectingoC/oFunitsofmeasure

PresstheoC/oFkeytoselectthedesiredtemperatureunitofmeasure.



TurntheTwoRedLaserPointersOn/Off

Pressthebacklight/laserbuttontoturnthelaserpointersONorOFF.



TakingMeasurements

TheIRT600candisplayDewPointTemperature(DP),AirTemperature(AT),InfraredSurface

Temperature(ST),andRelativeHumidity(%RH).Thebottomdisplaydigitsalwaysshowthe

SurfaceTemperaturereading.TheupperdisplaydigitsalternatelyshowAirTemperature,Dew

PointTemperature,orRelativeHumiditydependingonthemodethatisselected.Themulti‐color

statusLEDlight(locatedabovetheLCDdisplay)changescolortoindicatethelikelihoodofmildew

(seethe‘DetectingMildew’section).



1. PressthetriggeroncefirmlytoswitchthemeterON.

2. UsetheMODEbuttontoselectAirTemperature,DewPointTemperature,orRelative

Humidity%fortheupperdisplaydigits.Themeterwillrememberthedisplayselection

afterthemeterisswitchedOFF.

3. ForSurfaceTemperaturemeasurements,pointthemeter

towardthesurfaceundertest.Thelowerdisplaydigitsshow

thetemperatureofthesurfaceundertest.Forprecise

targeting,usethedualredlaserpointers(thebacklight/laser

pointerbuttonswitchesthepointersONorOFF).TheIR

sensorhasa12:1distance‐to‐spotratio(seeaccompanying

‘fieldofview’diagram).Forexample,ata30cmdistance,

themeasuredspotsizeis2.5cm.

4. PressthetriggerfirmlyagaintoswitchthemeterOFF.



IRSurfaceTemperatureMeasurementNotes

1. Theobjectundertestshouldbelargerthanthespot

(target)sizecalculatedbythefieldofviewdiagram(printed

onthesideofthemeterandinthisguide).

2. Beforemeasuring,besuretocleansurfacesthatare

coveredwithfrost,oil,grime,etc.

IRT600‐EU‐ENv1.49/135

3. Ifanobject'ssurfaceishighlyreflective,applymaskingtapeorflatblackpainttothe

surfacebeforemeasuring.Allowtimeforthepaintortapetoadjusttothetemperatureof

thesurfaceitiscovering.

4. Measurementscannotbemadethroughglass.

5. Steam,dust,smoke,etc.canobscuremeasurements.

6. Themeterautomaticallycompensatesfordeviationsinambienttemperature.However,it

cantakeupto30minutesforthemetertoadjusttoextremelywidechanges.

7. Tofindahotspot,aimthemeteroutsidetheareaofinterestthenscanacross(inanup

anddownorsidetosidemotion)untilthehotspotislocated.

DetectingMildew

Todetectmildew,takeaSurfaceTemperaturemeasurementasdescribedearlierbypointingthe

meteratthedesiredobject(s)andmovingthemeterslowly,notingthesurfacetemperatureof

theobject(s)undertest.



AlsonotetheAirTemperature,DewPointTemperatureandRelativeHumiditytolearnhowthese

relationshipsaffectmildewpotential.Themeterautomaticallydetectsthelikelihoodofmildew;

nonethelessitisusefultoseehowonemeasurementaffectsanotherandhowthecombinations

ofthesemeasurementsandcalculationsleadtoanaccuratemildewanalysis.



ThelikelihoodofmildewishighertheclosertheSurfaceTemperatureistotheDewPoint

Temperature.(TheDewPointtemperaturetakestheRelativeHumiditymeasurementinto

account,sincethehighertheRH,thehighertheDewPointTemperature).



ThemeterusestheAirTemperature(AT)andtheDewPointTemperature(DP)valuestocreatea

rangeoftemperaturesthatisdividedintothirds(seeaccompanyingdiagram).Theupper

boundaryistheAirTemperature(AT)andthelowerboundaryistheDewPointTemperature(DP).





Ifthesurfacetemperaturelieswithintheupperthirdtemperaturerangebetweentheair

temperatureandthedewpointtemperature,theLEDwillbegreen,indicatingthatthesurface

temperatureandhumidityarebothnormalandmildewisunlikely(seediagram).



Ifthesurfacetemperaturelieswithinthemiddlethirdtemperaturerangebetweentheair

temperatureandthedewpointtemperature,theLEDwillbeyellow(amber),indicatingthat

thereisalowtomoderatepotentialformildew.



Ifthesurfacetemperaturelieswithinthebottomthirdtemperaturerangebetweentheair

temperatureandthedewpointtemperature,theLEDwillbered,indicatingthatthereisahigh

probabilityofmildewpresentonthesurfaceundertest.



Forexample,iftheairtemperatureis25°Candtherelativehumidityis50%,thedewpoint

temperatureis13.8°C.Inthisexample,thelightwouldbegreenwhenthesurfacetemperatureis

between25and21.3°C;ayellowlightwouldindicateasurfacetemperaturebetween21.2and

17.4°C;andaredlightwouldindicateasurfacetemperaturebetween17.3and13.8°C.
