1 Introduction
Mettler-Toledo Thornton pH sensors type 3201-UPW
are low-maintenance electrodes withpressurized gel-
electrolyte,silver-iontrapandbuilt-intemperaturesensor.
2 Safety instructions
The sensor consists primarily of glass and should
behandledcarefully.Ifthesensoristobecleanedor

applicable to the handling of the sensor. Please take
extra care during installation/tting of the sensor to
ensurethatthepolymerthread(Pg13.5)doesnotsuffer
anydamage.

4 Installation and commissioning
1. On unpacking, check the sensor for possible
mechanicaldamageofthepHsensitiveglass,the
ceramic reference junction/diaphragm, the shaft
andtheVarioPin(VP)orISMconnector.Reportany
damageimmediatelytoyourMettler-ToledoThornton
supplier.
2. Removethewateringcapandbrieyrinsethesensor
with deionized water. Important: Carefully and
thoroughlyremovetheprotectivedropletofsilicone
sealantonthereferencejunction/diaphragmwiththe
enclosedknife,asshownonthegreenpictureson
thepacking.
3. Againrinsethesensorwellwithdeionizedwater.After
rinsing,thesensorshouldonlybedabbeddrywith
atissue.Donot rub thepHsensitiveglass,since
thiscanleadtoelectrostaticchargingandsluggish
response times.
4. Carefullycheckthe spacebehindthepHsensitive
glassforthepresenceofanyairbubblesandremove
same by gently swinging the sensor in a vertical
plane.
5. Pleaserefertotheinstructionmanualfortherelevant
housinginordertoinstallthesensorcorrectly.
6. ConnectthesensortothepHpreamportransmitter,
usingacablewithVarioPin(VP)orISMconnector.
Please refer to the wiring and terminal diagram
accompanyingthecable.
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
sensorisdippedinsuccessionintotwodifferentbuffer
solutions with known pH reference values and the
transmitteriscalibratedtothesebuffervalues.
5.2 Temperature sensor
TheintegratedPt1000temperaturesensorisprimarily
intendedforautomatictemperaturecompensationofthe
pHsignalduringcalibrationandnormaloperation.For
accurateindicationorcontroloftheprocesstemperature,
a further sensor temperature calibration may be
performed.
6 Maintenance
1. Carefully rinse the sensor tip and reference
junction/diaphragm with deionized water after
removalfromtheprocess.Undernocircumstances
should measuring solution containing solids be
allowedtodryontheseparts!
2. When the sensor isnot in operation,storeit with
sensor tip and reference junction/diaphragm well
submergedinto3MKCl.
