Chapter 1: Introduction
1.1 Introduction
The 9182 oxygen analyser is a one-channel analyser for the measurement of dissolved oxygen in
the boiler feedwater, economizers, condensers and more generally all thermal equipment using
water as a heat transfer liquid.
1.2 Principle of operation
The measurement of dissolved oxygen is based on the well-known Clark cell principle.
An oxygen-permeable membrane isolates the electrodes from the sample water, thus obviating the
need for sample conditioning. Other reducible or oxidizable ions do not interfere, because they
cannot pass through the gas-permeable membrane.
A constant voltage supply powers two electrodes, maintaining each at a constant potential.
A gold working electrode (cathode) reduces the dissolved oxygen to hydroxyl ions:
O2 + 2H2O + 4e- → 4OHA large silver counter electrode (anode) provides the oxidation reaction which occurs on its
surface:
4Ag + + 4Br - → 4AgBr + 4eThe reduction of oxygen is the current limiting reaction, thus making the cell current linearly
proportional to the dissolved oxygen concentration.
Electrochemical reactions and diffusion rates are temperature-sensitive. The measuring cell,
therefore, is equipped with a temperature sensor which allows an automatic temperature
compensation.

Λ Electrical connections should remain dry to ensure a proper operation of the
instrument.
Check the creeping of the cables when opening the transmitter.
Λ It is required to use shielded cables. This shielding should be connected to the
earth central shielding.
3.7 Mains connection
Electrical connection should be performed only by qualified personnel. The power supply accepts
100-240 VAC ± 10 %, (50/60 Hz) without changes in configuration. The terminal block for power
connections can be lifted from its header for easier installation. For safety reasons, it is required to
observe the precautions below:
• Use a three wire mains supply cable (2 core + PE) with a cross section between 0.35 and 2 mm2
(AWG 22 to 14) rated at 105 °C minimum. The external cable insulation should be cut as close
as possible from the terminal block.
• The instrument should be connected to the power supply by means of a breaker located close
to the instrument and be identified. The supply shall be fitted with an overcurrent protection
device rated at 20 Amp maximum.
• This breaker should switch off phase and neutral in case of electrical problems or when the user
wish to service the instrument. However the power supply earth must always be connected.
!
Before servicing the instrument, ensure that the power supply is switched
off.
3.8 Starting the transmitter
Before switching on the transmitter, make sure the site voltage corresponds to the instrument
voltage indicated on the identification plate.
3.9 Adjusting the display contrast
If your display contrast is not sufficient, you can adjust it with the potentiometer P1 (blue colour, see
figure page 3-2) which is located on the top left of the CPU board (after opening the enclosure).

Chapter 6: Calibrating the instrument
NOTE
See chapter 5 for programming the commands.
REMARK
Any result (calibration or measurement) is always brought back to the reference temperature
(25°C, 77°F). If the sample temperature is different from the reference temperature, it is required
to execute a temperature compensation which can be either manual or automatic.
6.1 Calibration of the temperature sensor
The temperature sensor is located in the dissolved oxygen measurement probe. It is factorypreadjusted but needs to be calibrated in the sample on site. This calibration must be realised
before the oxygen measurement calibration (slope + zero).

Chapter 7: Start up, maintenance and troubleshooting
7.1 Start up
7.1.1 Assembling the probe
The probe is composed of the following items:
1 : Nut
2 : Measuring electrode
3 : Probe body
4 : Membrane
5 : Filling screw
6 : Gasket
7-1
Oxygen analyser (ppb) - 9182 -
Proceed as follows for the assembling:
A. Screw the membrane † on the body till the dead stop ƒ.
B. Fill in the probe body with 5 ml of electrolyte by means of the syringe.
ð Check there is no impurity or bubble in the electrolyte .
C. Insert the electrode ‚ in the probe body until you meet a resistance. Do not force.
D. Complete the mounting by tightening the nut.
E. Mount the filling screw and its gasket. Tight it sufficiently to avoid any leaking of electrolyte or
external pollution from sample.
7-2
Oxygen analyser (ppb) - 9182 -
7.1.2 Probe connection
See figure page 3-2 for the electrical connection. The standard length of the cable is 10 m.
7.1.3 Main power supply connection
Install the ferrite on the mains supply cable as close as possible to the transmitter. Proceed to
the connections according to the drawing page 3-2.
7.1.4 Starting up the analyser
When switched on, the analyser operates an automatic test of its electronics and displays a first
value. Wait till stabilization of the measurement (max. 30 mn). You should not calibrate the analyser
before the temperature and the concentration are stable (See chapter 6).
Note 1: There is electrolyte in the probe, keep it head down when you remove it from the water.
Note 2: Never shake the probe during a calibration, it may provoke an introduction of oxygen
in the electrolyte and a temporary cell current increase.
7-3
Oxygen analyser (ppb) - 9182 -
7.2 Changing the membrane
Never take off the electrode before removing the electrolyte filling plug.
Never touch the membrane with the hands.
Never use a worn membrane.
•
Turn off the water supply. Remove the
connector from the probe.
‚ Unscrew the cell cap and remove the
probe.
7-4
Oxygen analyser (ppb) - 9182 -
7.2.1 Dismounting the membrane
A. Unscrew cap and gasket.
B. Unscrew nut.
C. Remove electrode without scratching the cathode.
D. Empty the electrolyte left in the probe.
E. Unscrew the worn membrane.
7-5
Oxygen analyser (ppb) - 9182 -
7.2.2 Mounting the new membrane
F. Screw the new membrane on the body till the dead stop.
G. Replenish the probe body with 5 ml of electrolyte. Check there is no impurity or bubble in the
electrolyte.
H. Preposition the electrode without forcing. It should take its place by simple gravity.
I. Screw the probe nut till the electrode meets a resistance.
J. Put back the cap and gasket, screw the cap to ensure watertightness.
7-6
Oxygen analyser (ppb) - 9182 -
7.3 Oxygen electrode rejuvenation procedure
After some months of operation (3 to 12 depending on sample oxygen concentration, plant shutdown frequency, ...), a dark AgBr coating may cover part of the silver anode.
This coating does not affect the measurement until more than 90% of the surface is contaminated.
When changing the electrolyte and membrane, visually check the silver anode.
If more than 2/3 of the surface is covered then an electrode rejuvenation according the following
procedure is needed:
- soak the anode in 10 % ammonia for about 1 hour then rinse it with demineralised water and wipe
it with a soft cloth,
- if the ammonia cleaning is not sufficient, rejuvenation of the silver electrode has to be done by repolishing softly (coating is a only few microns thick) the areas covered with silver bromide with soft
abrasive (N° 400 to 600). After polishing, rinse the anode with demineralised water and wipe it
with a soft cloth.
The cleaned electrode performs immediately as well as a new electrode.
Obviously, as per any operation concerning a sensing element, recalibration is required.
7.4 Functional troubleshooting
Problem: Excessive time for stabilization or no stabilization during calibration in the air.
Causes and solutions:
a) The sample temperature is further to the ambient temperature: 6°C (43°F) in water and
35°C (95°F) in the air so that the temperature drift provokes a reading drift
! Do not wait till the probe temperature meets the external temperature (use the
temperature compensation).
b) There is an electrolyte leak (through the membrane). The current is too high because of an
excessive penetration of oxygen
! Change the membrane .
c) There is an important pollution of the electrolyte due to an incorrect adjustment of the filling
screw
! Change the electrolyte. Check there is a gasket and the screwing. Check the Teflon
band is correctly positioned.
d) The electrode is not correctly mounted in the probe body: there is an important looseness
between the membrane and the golden cathode
! Tighten the electrode screw (rep 3 page 7-1).
e) The membrane holder is incorrectly screwed. Risk of electrolyte pollution
! Change the electrolyte and tighten correctly the membrane holder.
7-7
Oxygen analyser (ppb) - 9182 -
f) Lack of humidity because of an excessive temperature
! Use a calibration cap (see spare parts list)
g) There is humidity or water in the probe connector
! You notice a high unstability. Dry the connector and check it is correctly screwed.
h) The golden cathod surface is damaged (scratch or holes due to important shocks)
! Do not polish the surface. Change the electrode.
i) Mud or particles on the golden cathod
! Clean the cathod with an absorbant soft tissue and rinse the membrane.
j) The electrolyse potential does not equal - 0.85 V
! Enter the correct value
k) Cable or connections damaged when the probe has been replaced
! Check the connexion to the transmitter. If the connexion is correct check the
connections of the probe connector.
l) The probe is incorrectly positioned (see § 7.1.4 page 7-3 - note 1). The electrolyte leaks and air
bubbles input the cathod
! Put the probe in the correct position, head down.
Problem: No significant current increase when the probe is in the air for the calibration
Causes and solutions:
a) There is an important pollution of the electrolyte due to an incorrect adjustment of the filling
screw
! Change the electrolyte. Check there is a gasket and the screwing. Check the
Teflon band is correctly positioned or that the probe is not damaged.
b) The membrane holder is incorrectly screwed. Risk of electrolyte pollution
! Change the electrolyte and tighten correctly the membrane holder.
c) The membrane has been torn
! Change the membrane.
d) The electrode is not correctly mounted in the probe body: there is an important looseness
between the membrane and the golden cathode
! Tighten the electrode screw (rep 3 page 7-1).

Oxygen analyser (ppb) - 9182 -
e) Cable or connections damaged when the probe has been replaced
! Check the connection to the transmitter. If the connection is correct check the
connections of the probe connector (See appendix 4 for the connector
connections).
f) The membrane is worn
! Change the membrane.
g) There is a AgBr (dark green) deposit on the silver
! Polish the silver tube with soft abrasive (N° 400 to 600)
Problem: Important instability in measuring mode
Causes and solutions:
a) There is humidity or water in the probe connector
! Dry the connector and check it is correctly screwed.
b) Incorrect connexion
! Check the connections of the transmitter to the probe.
c) There are bubbles close to the cathod
! Replenish the electrolyte holder and check there is no bubble between the cathod
and the membrane.
d) The probe is violently shaked
! Check the fixation and the stability.
e) Important electromagnetic interferences close to the probe or transmitter cable
! Find a better place for the cable and check the EMC level.
f) Temporary interference with other gas
! Mainly with H2S
g) Flowrate too weak (50 ml/h minimum)
! Change the probe location
h) Mud from an heterogen sample damages the membrane
! Install a deflector or change the probe location
Problem: Lack of accuracy
Causes and solutions:
a) The membrane permeability has changed (dirt deposit)
! Calibrate the analyser and check if the concentration is back to normal.
7-9
Oxygen analyser (ppb) - 9182 -
b) Pollution of the electrolyte
! Check the parts to screw (membrane, filling screw) and change the electrolyte.
c) Leak of electrolyte
! Check the parts to screw (membrane, filling screw) and change the electrolyte.
d) Interferences, mainly with H2S
! If the level of H 2S (or other pollutant) is stable, take into account its concentration
to determine the O 2 concentation.
e) Error during calibration or incorrect calibration
! Calibrate again to check the parameters. If the error is confirmed, check the
calibration current (too high, too low or unstable) and the concentration in the air.
Refer to the problems described above.
f) The temperature calibration has not been done
! Check the temperature given by the transmitter and calibrate it (see page 6-2). If
you have chosen the manual compensation check the value is correct.
g) There are bubbles close to the cathod
! Replenish the electrolyte holder and check there is no bubble at the bottom.
h) Flowrate too low (4 l/h minimum)
! Increase the flowrate.
i) The sample temperature or pressure is out of the specifications
! Change the probe location or modify the sample so that it meets the specifications.
j) Mud or particles on the golden cathod
! Clean the golden cathod with an absorbant tissue and rinse the membrane.
k) The electrolyse potential is not equal to -0.85 V
! Enter the correct value.
Other problems
a) The probe current is null
! There is no electrolyte in the probe (leak).
b) The probe current is negative
! Connexion problem to the anode circuit (loose contact).
! AgBr deposit on the anode
c) The sample temperature corresponds to the specifications but there is an error on the
temperature
! There may be a short-circuit on the temperature connection.
