Overview

pHOverview

pHisaunitofmeasure(rangingfrom0to14pH)indicatingthedegreeofacidityoralkalinityofa

solution.SolutionswithapHlowerthan7areconsideredacidic,solutionswithapHhigherthan

7areknownasbases,andsolutionswithapHofexactly7areconsidered‘neutral’.

ThepHscaleislogarithmicso,forexample,ifsample‘A’is1pHlowerthanSample‘B’,then

Sample‘A’is10timesmoreacidicthanSampleB.Adifferenceof1pHrepresentsaten‐fold

differenceinacidity.

GettingStarted

Fornewmeters,removethebatterycap(1)atthetopofthemeterandinstall2batteries

observingcorrectpolarity.

Removethecapfromthebottomoftheinstrument(7)toexposetheflatsurfaceelectrodeand

referencejunction.

Beforefirstuse,rinsetheelectrodewithcleantapwaterandwipedry.

Thespongeshouldbekeptmoistenedatalltimestoensureaccuracy.

ReplacingElectrodes

ThePH90isshippedwithaflatsurfacepHelectrodeattached(7).Electrodelifeislimited,andis

dependenton(amongotherfactors)frequencyofuseandcare.Iftheelectrodeneedstobe

replaced,followthesestepsforremovingandconnectingelectrodes.ReplacementpH

electrodes(partnumberpH95)areavailablefromExtechInstruments.

1. Unscrewtheelectrodecollar(6)clockwise,andremoveitcompletely.

2. PullthepHelectrodemoduleoutfromthetester.

3. Carefully,pluganewelectrodemoduleintothetestersocket.

4. Replaceandtightentheelectrodecollartoensureagoodseal.

AutomaticElectrodeRecognition

Whenthemeterispowered,itrecognizesthetypeofelectrodethatisconnectedanddisplays

theappropriateunitofmeasure.Attachtheelectrodebeforepoweringthemeter;neverpower

themeterwithoutanelectrodeattached.

PoweringtheMeter

Thebatteriesarealreadyinstalledinthemeter.Pressthepowerbutton(3)topowerONorOFF.

Thedisplayedbatteryindicatorletstheuserknowthestatusofthebatterystrength.TheAuto

Powerofffeatureshutsthemeteroffautomaticallyafter10minutesofinactivitytopreserve

batterylife.

Operation

UnderstandingthePH90Display

Whenanelectrodeisplacedinasolution,themaindisplayindicatesthepHreadingwhilethe

lowerdisplayshowstemperature.

pHCalibration

Atwopointcalibrationwithabufferof7and4or10(whicheverisnearesttotheexpected

samplevalue)isalwaysrecommended.Forbestaccuracy,alwayscalibrateatthesample

temperature.

1. CheckthatthepHiconisdisplayedontheLCD.

2. DiptheelectrodeintothepH7buffersolution.Stirgentlyandwaitforastablereading.

3. PressandholdtheCALbutton(3)toentercalibrationmode.

4. TheLCDwilldisplaytheCALiconandthenflash7.00.

5. WhencalibrationiscompletethemeterwillstopflashingandindicateSAandEND.

6. Rinsetheelectrodewithcleantapwaterandwipedry.

7. DiptheelectrodeinpH4(orpH10)buffersolution.

8. Stirgentlyandwaituntilthedisplayisstable.

9. PressandholdtheCALbuttontoentercalibrationmode.

10. TheLCDwilldisplaytheCALiconandthenflash4.00or10.00.

11. Whencalibrationiscompletethemeterwillstopflashingandindicate%(percentofslope),

SAandEND.

12. AfterthecalibrationofpH4orpH10,thedisplaywillindicatetheslopepercentage(PTS),

indicatingthestatusoftheelectrode.

13. IfthePTSis<70%or>130%theelectrodemustbereplaced.Aslopeof100%isideal.



Note:TheSAiconwillnotappearifthecalibrationfails.

Note:CalibratewithapH7bufferfirstandthenfollowwithapH4orpH10calibration.
