Introduction



ThankyouforselectingtheExtechInstrumentsModelRH25HeatIndexPsychrometer.TheRH25

measuresTemperatureandRelativeHumidity(usingprecisioncapacitanceRHsensor).TheRH25

alsocalculatesanddisplaysHeatIndex,DewPoint,WetBulb,andWetBulbGlobetemperatures.

TheHighTemperatureAlarmfeaturealertstheuserwhenHeatIndexorWetBulbGlobelevels

exceeduser‐presetlimits.

DataHoldandMIN/MAX/AVGmemoryutilitiesmakeiteasiertorecallimportantdata.

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

reliableservice.Pleasevisitourwebsite(www.extech.com)tocheckforthelatestversionofthis

HOLD:PresstoenterDataHold(readingfreezesondisplay).PressagaintoexitDataHold.

MODE:Presstostepthroughthemeasurementmodes:TEMP(Temperature),RH(Relative

Humidity),HI(HeatIndex),DP(DewPoint),(WB(WetBulb),andHI/WB(WetBulbGlobe).



Poweringthemeter

PressPOWERtoswitchmeterON.Themetershowsalldisplayiconsmomentarilyasitswitches

ONandthentheTEMPiconandthetemperaturereadingwilldisplay.Themeterwillalsoemita

chirpsoundasitswitchesON.

ToswitchthemeterOFF,pressandholdthePOWERbuttonforatleast2seconds.



MAX/MIN/AVGMemory

WiththemeterpoweredON,pressPOWERbuttonmomentarily.TheMAXiconwillappearand

themeterwilldisplayonlythehighestreading.

PressPOWERagain;theMINiconwillappearandthemeterwillonlydisplaythelowestreading.

PressPOWERagain;theAVGiconwillappearandmeterwillonlydisplaytheaveragereading.

PressPOWERagaintoexit(theMAX/MIN/AVGiconswillswitchOFF).



DataHold

WiththemeterpoweredON,presstheHOLDbuttonmomentarily.TheHOLDiconwillappear

andthecurrentreadingwillfreezeonthedisplay.PressHOLDagaintoexit(theHOLDiconwill

switchOFF).



AutomaticPowerOFF(Sleep)Mode

ThemeterswitchesOFFautomaticallyafter15minutesofinactivity.Todefeatthisfeature

temporarily:WiththemeterswitchedOFF,presstheHOLDandPOWERbuttonssimultaneously

untilthemeterdisplaysthescreenshownbelow.Now,theusermustswitchthemeterOFF

manuallybypressingandholdingthePOWERbuttonforatleast2seconds.Notethatthenext

timethemeter’spoweriscycled,theAutoPowerOFFutilitywillagainbeactive.

SelectingoC/oFunitsofmeasure

WiththemeterOFF,pressandholdthePOWERandMODEbuttonssimultaneouslyuntiltheunit

ofmeasureappearsonthelowerrightcorneroftheLCD.UsetheMODEbuttontoselectthe

desiredunitofmeasure(oCoroF).PressPOWERtwicetosteppastthealarmsettingsuntilthe

normalmeasurementmodeisdisplayed.

HighAlarmforHeatIndexandWetBulbGlobetemperature

1. WiththemeterOFF,pressandholdthePOWERandMODEbuttonssimultaneouslyuntilthe

temperatureunit‘C’or‘F’appearsonthelowerrightcorneroftheLCD(ifdesired,usethe

MODEbuttontoselectthedesiredunitofmeasure).

2. PressthePOWERbuttontosteptotheHeatIndex(HI)AlarmON/OFFdisplay.

3. UsetheMODEbuttontoselectON(A‐on)orOFF(A‐oF);seedisplayexamplesbelow:

4. PressPOWERtosteptotheHeatIndextemperatureAlarmlimitvalue.Seeexamplebelow:



5. PresstheMODEbuttonmomentarilytochangethevalueinsmallsteps.Pressandholdthe

MODEbuttontoscrollquickly.

6. WhenthedesiredHeatTemperaturealarmlimitisdisplayed,pressthePOWERbuttonto

continuetotheWetBulbGlobetemperatureAlarmprogrammingscreens.

7. Repeatsteps3‐6toprogramtheWetBulbGlobetemperatureON/OFFandAlarmlimits.

UsethePOWERbuttonwhendonetostepbacktothenormaloperatingmode.

8. Thedefaultsettingsare27.8oC(82.0oF)forHeatIndextemperaturealarmlimitsand28.0oC

(82.4oF)forWetBulbGlobetemperaturealarmlimits

9. Wheneitheralarmlimitisexceeded,themetercontinuouslybeeps.Todeterminewhich

alarmissounding,checktheHI(HeatIndex)andWB/HI(WetBulbGlobe)temperature

displaystoseewhichunitofmeasureisblinking,thatwillindicatethetrippedalarm.

10. TosilenceanalarmtheusermusteitherswitchthealarmOFForchangeitsalarmlimitvalue.
