lybeforeputtingtheelectrodeintooperation,inorder

to ensure faultless operation.

1. Onunpacking,checktheelectrodeformechani-

caldamageofthepHsensitiveglassandshaft.

ReportanydamageimmediatelytoyourMETTLER

TOLEDOsupplier.

trodeshouldonlybedabbeddrywithatissue.Do

airbubblesandremoveanyairbubblesbyshak-

ingtheelectrodeslightlyinaverticaldirection.

4. Placetheelectrodeintothehousingasdescribed

intheinstructionsforthehousing.

5. ConnecttheelectrodeandthepHtransmitterwith

5 Operation

5.1 Calibration of the electrode and pH transmitter

FortheInPro3030electrodea2-pointpH-calibration

isrecommended.Beforecalibration,rstremovethe

wateringcap.Tospeeduptheresponsetimeofthe

electrode after long transport and storage periods,

andbeforecalibration,diptheelectrodeintobufferpH

7,bufferpH4andbufferpH7again,eachtimefor

aboutoneminute.Theelectrodeisthendippedsuc-

cessivelyintotwodifferentbuffersolutionswithgiven

pHreferencevaluesandthetransmittercalibratedto

thesebuffervalues.NormallyyoustartwithbufferpH

7fordeterminingthe0-pointandthenbufferpH4or

9fordeterminingtheslope.Inthecaseofmicropro-

cessor-basedtransmitterswithbufferrecognition,the

orderofthetwochosenbuffersolutionsisirrelevant.

Wheneverpossible,atemperaturesensorshouldbe

connectedtothetransmitterand«automatictempera-

turemeasurement»selectedthere.

Pleaserefertotheinstructionmanualofthetransmit-

terforfurtherdetails.

5.2 Sterilization of the electrode

The InPro 3030 electrode can be sterilized either

through autoclaving or through in-situ sterilization

with steam or superheated fermentation medium.

Sterilization temperatures above 140 °C are not al-

lowed,andexcessivesterilizationtime(forinstance

t>30min at 140°C) could notably shorten the life

time ofthe electrode.Repeated sterilization and/or

autoclavingoftheelectrodecanleadtoaslightcol-

orationoftheelectrolyte.Thiscolorchangedoesnot

effectthefunctioningoftheelectrode.

6 Maintenance

1. Carefullyrinsetheelectrodetipanddiaphragmwith

de-ionizedwateraftereachproductioncycle.Under

no circumstances must measuring solution be al-

lowedtodryontheseparts!

2. Whentheelectrodeisnotinoperation,storeitwith

electrodetipanddiaphragmwellsubmergedinto

9823/3MKClor9816/Viscolyt™electrolyte.

3. Iftheelectrodeisstoredmountedinitshousing,

thesameruleasdescribedinpoint2applies,but

thestorageelectrolytehastobeslightlymodied,

with2partsofbuffersolutionpH9.2to10parts

ofelectrolyte,thisinordertoavoidcorrosionof

4. Ifaelectrodeisstoreddryforafewdaysbymis-

take,letitsoakinthenormalstorageelectrolyte

forseveralhoursbeforeuse.

5. Occasionallychecktheconnectorforpossibletrac-

esofmoisture.Ifnecessary,cleanwellwithde-ion-

izedwateroralcohol,andafterwardsdrycarefully.

7 Trouble-shooting (sluggish response time,

insufcient sensitivity etc.)

TheglassmembranecanbereactivatedusingaHF

solution (order no. 51 319 053). The electrode tip

(onlypHsensitiveglasspart) isimmersedintothe

HFsolutionforaperiodofabout5minutes,isthen

immediately and thoroughly rinsed with de-ionized

waterandthereafterstoredinbuffersolutionpH4(see

Chapter6)uptothediaphragmfor12hours.

Possibleproteinprecipitationandblockageofthedi-

aphragmcan be treated withour special electrode

cleaner(orderno.51340068).However,useofthe

diaphragmcleaner(orderno.51340070)isnormal-

lynotnecessaryforthiselectrodetype,asthebuilt-in

silver-iontrappreventstheformationofsilversulde

contamination.

Also,checktheconnectorforpossibletracesofmois-

ture.Ifnecessary,cleanwellusingde-ionizedwater

oralcohol,andafterwardsdrycarefully.

8 Disposal

Ifnorelativeofcialregulationsareinforce,usedor

defectiveInPro 3030electrodesand thepackaging

canbedisposedoffasordinaryhouseholdwaste.

9 Warranty

Intheeventofmanufacturingfaults,12monthswar-

rantyfromdateofproductionisgranted.
