Instructions for Use of the SE102-AN pH Sensor
!
WARNING – Failure to observe this warning
may result in serious injury.
Read these instructions for use, observe the Specifi­
cations, and follow the Safety Instructions.
1 Safety Instructions
Hazards due to temperature or aggressive media are
possible, depending on the location of use. There­
fore, the operation and servicing of the sensor shall
only be carried out by suitably trained personnel
authorized by the operating company.
Be sure to wear safety goggles and gloves when
cleaning or calibrating a sensor using acid or alka­
line solutions.
2 Sensor Description and Intended Use
The SE102­AN pH sensor is equipped with 1 m fixed
cable. Connection to the transmitter (e.g. Portavo) is
made via a DIN 19262 coax connector and a 4 mm
spring connector.
The integrated temperature detector provides auto­
matic temperature compensation during calibration
and operation of the sensor. The sensor is designed
for simultaneous measurement of pH and tempera­
ture in industrial processes, particularly in the field of:
drinking water, wastewater, water processing.
The markings on the sensor or on the packaging label
include the following information:
Manufacturer of sensor
SE102­AN Model
0 … 14 pH range
­5 … 100 °C Temperature range
CE conformity mark
The quality certificate and the packaging label pro­
vide the serial number and the sensor data of the final
inspection. The sensor fits into the sensor quiver of a
portable transmitter from the Portavo series.
The O­ring

seals the quiver.
3 Commissioning
•
On unpacking, check the sensor for mechanical
damage. Report any damage to your Knick service
team.
•
Remove the watering cap and briefly rinse the sen­
sor with pure water. After rinsing, the sensor should
only be dabbed dry. Do not rub the pH­sensitive
glass, since this can lead to electrostatic charging
and sluggish response times.
•
Connect the sensor cable with the transmitter.
4 Operation
Note: Always open the closure
4
before calibrating
or measuring. Refill electrolyte if necessary.
4.1 Calibrating the Sensor
2­point calibration is recommended for the SE102­MS
sensor. The sensor is dipped successively into two
different buffer solutions with given pH values (e.g.,
pH 7.00 and pH 4.00). Please refer to the user manual
of the pH transmitter for further details.
4.2 Positioning
The sensor can be operated vertically or inclined up
to 45° off horizontal.
5 Maintenance and Cleaning
Never keep or store the sensor dry! You should store
the sensor with fitted watering cap containing elec­
trolyte (3 mol/l KCl). If the sensor is to be inserted into
the quiver of a Portavo series measuring device, the
screwed­on watering cap (9) must be replaced by the
included flexible watering cap (10).Close the filling
hole
4
when storing the sensor. Clean the sensor
(glass membrane and junction) with clean water after
each production cycle and regularly in case of heavy
pollution.
