Introduction

ThankyouforchoosingtheExtechDissolvedOxygen/TemperatureMeterwhichsimultaneously

displaysDissolvedOxygenandTemperatureorOxygeninairandTemperature.Unitsofmeasure

aremg/lforDissolvedOxygen,%forOxygeninair,andoC/oFfortemperature.Oxygenis

measuredwitharemotesensorthatalsocontainsathermistorformeasuringairtemperature.

Advancedfeaturesincludealtitudeand%saltcompensation,datahold,autoshutoff,and

Min/Maxrecording.

GettingStarted

Note:Thedissolvedoxygenprobeassemblymaybeshippedfromthefactorydry.Ifthe

probedoesnotcontainelectrolytesolution,refertotheElectrolyteReplacementsection

belowforinformationonaddingtheelectrolytesolutionpriortoinitialuse.

FillingtheElectrolyteContainerPriortoInitialUse

1. Unscrewandremovetheelectrolytecontainerfromthetipof

theprobe.

2. Filltheelectrolytecontainerwithnewelectrolyte.

3. Screwtheelectrolytecontainerbackontotheelectrodeholder

andprobehandle.ExcessElectrolytemaybeforcedout

throughthethreads.Wipeclean.

4. Lightlytaptheprobetoremoveairbubbles.



Calibration

Forfirsttimeuseorafterlongperiodsofnon‐use,calibratetheinstrumentusingtheprocedure

below.Theprocedureshouldbeperformedinanopen,well‐ventilatedarea.

1. Connecttheoxygenprobeplugtotheprobeinputsocket.

2. SwitchONthemeterbypressingthePower/ESCbutton.

3. Thelowerdisplayshouldindicatethe%O2unitsymbolandatemperaturevalue.

4. Theupperdisplaywillbeginfluctuating.Waitapproximately3minutesfortheupper

displaytostabilize.

5. PresstheHOLDbuttonandthedisplaywillshowtheHOLDicon.

6. PresstheRECbutton.Thedisplaywillshow"CAL"flashingandthemeterdisplaywill

begincountingdownfrom30tozero;themeterwillthendisplaytheENDicon.

7. Theupperdisplaywillshowavalueapproximately20.9or20.8(typicalconcentrationof

oxygeninair).

DissolvedOxygen(DO)Measurements

MeasurementPreparation

Beforetakingmeasurements,performthecalibrationdescribedaboveifnecessary.

TakingMeasurements

1. PressandholdtheFunctionbuttonforatleast2secondstochangefrom%O2tomg/Lor

frommg/Lto%O2.ForDOmeasurementsselectmg/L(milligramsperliter).

2. Immersetheprobeinthesolutionundertest.Foroptimumautomatictemperature

compensation,immersetheprobetoadepthofatleast4"(10cm).

3. Waituntilthedisplaystabilizes.

4. Thevelocityoftheliquidcomingintocontactwiththeprobemustbeatleast0.6to1

ft/min(0.2to0.3m/s).Ifthesolutionisstanding,stirthesolutionwiththeprobeoruse

anagitator.

5. Rinsetheprobewithcleanwateraftereachuseandcovertheprobeheadwiththe

probeheadprotectivecover.

OxygeninAir(%O2)Measurements

Beforetakingmeasurements,performthecalibrationdescribedearlierifnecessary.

TakingMeasurements

1. PressandholdtheFunctionbuttonforatleast2secondstochangefrommg/Lto%O2if

necessary.Foroxygeninairmeasurementsbesuretoselect%O2.

2. Holdtheprobeintheareaundertestandwaituntilthedisplaystabilizes.

TemperatureMeasurements

Thelowerdisplaywillindicatethetemperatureofameasuredsolutionorthetemperatureof

theair(dependingonwhattypeofmeasurementtheuserisperforming).Tochangethe

Theprobehead(onthetipoftheprobe)holdsathinTeflon®membraneandanelectrolyte

container.Calibrationerrorsorreadingerrorscouldindicatelossofelectrolyteora

dirty/damagedmembrane.Themembraneisverydelicateandcaneasilybedamagedifit

comesincontactwithsolidobjects.ReplacementprobeheadsareavailablefromanExtech

distributor.

Replacementprocedure

1. Unscrewtheprobeheadandemptytheoldelectrolytefromthecontainer.

2. Fillthenewprobehead/electrolytecontainerwithelectrolyte.

3. Screwtheprobeheadontotheprobehandle.Excesselectrolytemaybeforcedoutthrough
