4 Installation and commissioning

1. On unpacking, check the sensor for possible

mechanical damage of the pH sensitive glass,

the diaphragm, the shaft and the VarioPin (VP)

connector.Reportanydamageimmediatelytoyour

METTLERTOLEDOsupplier.

2. Remove the watering cap and briey rinse the

sensor with deionized water. Carefully remove the

protectiondropletofsiliconeonthediaphragmwith

theenclosedknife,asshownonthegreenpictures

onthepacking.

3. Againrinsethesensorwellwithdeionizedwater.After

rinsing,thesensorshouldonlybedabbeddrywith

atissue.Donotrub the pH sensitiveglass,since

thiscanleadtoelectrostaticchargingandsluggish

response times.

4. Carefullycheckthespace behind thepHsensitive

glassforthepresenceofanyairbubblesandremove

same by gently swinging the sensor in a vertical

plane.

5. Pleaserefertotheinstructionmanualoftherelative

housinginordertoinstallthesensorcorrectly.

6. Connect the sensor to the pHtransmitter, usinga

cablewithVarioPin(VP)connector.Pleasereferto

thewiringandterminaldiagramaccompanyingthe

cable.

7. For electrodes with Pt100 temperature sensors,

3-wiretechniqueisrecommendedinordertoobtain

best measurement accuracy. Please refer to the

cable and transmitter instruction manuals for the

correspondingcablewireconnections.

8.ForInPro3200SGelectrodes,withanadditionalPt

ringforsolutionground,connectthecorresponding

blue wire in the VP-cable to your transmitter in

accordance with instructions in the connection

diagramm of VP-cable and/or in the transmitter

instruction manual. For ORP measurement (sep.

transmitter needed) connect solution ground with

ORP input.

5 Operation

5.1 Calibration of the sensor and pH transmitter

For InPro 3200 sensors, a 2-point calibration is

recommended. After removing the watering cap,

the sensor is dipped in succession into two different

buffersolutionswithgivenpHreferencevaluesandthe

transmitteriscalibratedtothesebuffervalues.

5.2 Sterilization of sensor

Inthecaseofsterileprocesses,such as infermenta-

tionapplications,thesensorsaresterilizedpriortothe

productioncycle.Autoclavingofthewholefermenter/re-

actorunit including pH electrode is possible with this

sensor type. Sterilization can also be effected in-situ

bymeansofsteamorsuperheatedprocessmediumin

contactwiththelowersensorparts.

5.3 Temperature sensor

The integrated Pt100/1000 temperature sensor

is primarily intended for automatic temperature

compensationofthepHsignalduringcalibration and

normal operation, and notfortheaccurateindicationor

controloftheprocesstemperature.

6 Maintenance

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

deionizedwateraftereachproductioncycle.Under

no circumstances must measuring solution be

allowedtodryontheseparts!

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

sensor tip and diaphragm well submerged into

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

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

sameruleasin2)above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housingparts.

4. Ifasensorisstoreddryforafewdaysbymistake,let

itsoakinthenormalstorageelectrolyteforseveral

hoursbeforeuse.

5. Occasionallychecktheconnectorforpossibletraces

ofmoisture.Ifnecessary,cleanwellwithdeionized

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

7 Trouble-shooting

At sluggish response time (e.g.after alonganddry

storage period), reactivation of the pH sensitiveglass

maybenecessary.DipthepHsensitiveglass(butno

furthersensorparts!)intoReconditioning(HF)Solution

(articleno.51319001)for5min.Afterwards,rinsewell

withdeionizedwaterandletsensortipanddiaphragm

soakinreferenceelectrolyteforminimum12hours.

Rapidly increased resistance of reference electrode

and/or drift could be signs of protein precipitation. Use

CleaningSolutionPepsin/HCl(articleno.51340068)

toremovesuchprecipitation.Atrepeatedproblemsof

thistype,considerswitchingtosensorswithFriscolyt™

basedgelelectrolyte.

8 Disposal

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

defectiveInPro3200sensorsandthepackagingcanbe

disposedofasordinaryhouseholdwaste.

9 Guarantee
