2 Safety instructions

The sensor consists primarily of glass and should

behandledcarefully.Ifthesensoristobecleanedor

calibratedusingacidoralkalinesolutions,safetygoggles

andglovesshouldbeworn.Localsafetyregulationsare

applicable to the handling of the sensor. Please take

extra care during installation/tting of the sensor to

ensurethatthepolymerthread(Pg13.5)doesnotsuffer

anydamage.

Werecommendthatthesensormayonlybeinoperation

4 Installation and commissioning

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

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

ceramic reference junction/diaphragm, the shaft

andtheVarioPin(VP)orISMconnector.Reportany

damageimmediatelytoyourMettler-ToledoThornton

supplier.

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

with deionized water. Important: Carefully and

thoroughlyremovetheprotectivedropletofsilicone

sealantonthereferencejunction/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fortherelevant

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

6. ConnectthesensortothepHpreamportransmitter,

usingacablewithVarioPin(VP)orISMconnector.

Please refer to the wiring and terminal diagram

accompanyingthecable.

5 Operation

5.1 Calibration of the sensor and pH transmitter

For 3201-UPW sensors, a 2-point calibration is

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

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

solutions with known pH reference values and the

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

5.2 Temperature sensor

TheintegratedPt1000temperaturesensorisprimarily

intendedforautomatictemperaturecompensationofthe

pHsignalduringcalibrationandnormaloperation.For

accurateindicationorcontroloftheprocesstemperature,

a further sensor temperature calibration may be

performed.

6 Maintenance

1. Carefully rinse the sensor tip and reference

junction/diaphragm with deionized water after

removalfromtheprocess.Undernocircumstances

should measuring solution containing solids be

allowedtodryontheseparts!

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

sensor tip and reference junction/diaphragm well

submergedinto3MKCl.

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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

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

storageperiod)isanindicationthatreactivationofthepH

sensitiveglassmaybenecessary.DipthepHsensitive

glass(butnofurthersensorparts!)intoReconditioning

(HF)Solution(METTLERTOLEDOproduct,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.

8 Environmental protection

Waste electrical products should not be

disposedofwithhouseholdwaste.Please

recycle where facilities exist. Check with

yourLocalAuthorityorretailerforrecycling

advice.

9 Warranty

Intheeventofmanufacturingfaults,12monthswarranty

from date of production is granted.
