Section 3 Introduction
3.1 What you have received
3.1.1 C1100 electrochemical sensor
The sensor may be delivered separately or as part of an ORBISPHERE system, depending on
the individual order.
The sensor (as illustrated in Figure 2 above) will be delivered fitted with a plastic screw-on
storage cap to protect the sensor head. This is held in place with a plastic collar for the
C1100-S00 sensor, or a stainless steel collar for the C1100-T00 sensor.
A plastic screw-on base is also provided to protect the connection socket, and which also
provides a suitable stand for the sensor during maintenance procedures, and when not in use.
3.1.2 Protection caps
One protection cap with grille (part number 33051-SG as illustrated in Figure 3 above) will be
delivered as standard with each sensor.

Introduction
3.1.3 Sensor recharge kit
A recharge kit (as illustrated in Figure 4 below) should have been ordered with the sensor as
this will be required to initially make the sensor operational. It is also required for sensor
cleaning and membrane replacement procedures.
Note: The recharge kit for ozone has a green sticker on the front of the box.
The kit contains:
•four recharge cartridges with pre-mounted membrane and electrolyte. The type of
membrane mounted in the cartridge will be specific to the kit ordered
•anode cleaning tools
•a set of five cotton washers
•a set of replacement O-rings
•a set of replacement Dacron®mesh patches
The black anode cleaning tool (Figure 5) is used to clean the anode of any deposits or residue
that may have formed. It is doubled-ended so it can be used for two membrane replacement
processes, each end being used once.
The cotton washers provide additional protection against the formation of deposits and residue
on the center electrode and anode, which prolongs the time period required between sensor
maintenance.
The Dacron®mesh patches provide protection to the membrane.

Introduction
3.2 Sensor components
The following illustration shows the assembled sensor with the storage cap and sensor collar
removed and the exploded view of the main sensor components. To remove the storage cap,
you will first have to unscrew and remove the sensor base.
3.3 Basic principle of operation
In its simplest form, the electrochemical sensor consists of one center electrode (cathode) and
one counter electrode (anode) immersed in an electrolyte solution which is separated from the
liquid sample by a gas permeable membrane. An electronic circuit is linked to the anode and
cathode. Through an applied voltage, current will flow between the anode and the cathode.
A guard ring electrode surrounds the center electrode in order to reduce the influence of other
gases on the center electrode, and therefore improving analysis stability. The sensor head is
covered with a protection cap to protect the membrane.
Ozone penetrating through the membrane into the cell reacts with the electrolyte which then
undergoes a reaction at the cathode, causing a measurable electric current to flow. This current
is proportional to the amount of gas entering the cell, which in turn is proportional to the partial
pressure of gas in the sample outside the cell.
The result is shown as gas concentration, which can then be displayed with a choice of several
measuring units, according to instrument setup.
The sensor also includes “smart sensor technology”, implemented using an RS485 interface.
The sensor electronics perform four functions:
•Apply constant voltage to the anode
•Measure the current flowing through the sensor
•Compensate for temperature variation in the liquid sample
•Convert the cell’s electric current into an analog signal for sensor output

Section 4 Installation
4.1 Sensor preparation
Your C1100 electrochemical sensor has been thoroughly cleaned and tested at the factory
before shipment. It has been shipped with a cartridge containing a membrane and electrolyte
pre-installed to protect the sensor head. This cartridge must be removed and replaced with a
new one prior to first use to make it fully operational. The new cartridge is included in the sensor
recharge kit (see additional details in Sensor recharge kit on page 12). You will also need one of
the mesh patches included with the kit.
The following instructions detail the steps required to make the sensor operational. Should you
have any questions, your Hach Lange representative will be pleased to help.
CAUTION
Avoid all eye and skin contact with the electrolyte in the sensor and replacement
cartridge. If eyes or skin come into contact with electrolyte, rinse immediately with water.
In addition, the electrolyte can permanently stain clothing so exercise care in handling. It
is highly recommended to wear protective gloves and glasses during this process.
Note: It is advisable to perform this procedure with the plastic sensor base installed so as to avoid any
damage to the connection socket and also to provide a suitable stand for the sensor when required.
1. Hold the main body of the sensor and
unscrew the protection cap locking washer
by turning counter-clockwise. Remove it from
the sensor and put to one side.
2. Pull/twist off the protection cap and put to
one side. Remove the Dacron®mesh from
inside the cap and discard it.

16
Installation
3. Hold the sensor with the membrane facing
down to avoid spilling any electrolyte, then
carefully unscrew the shipment cartridge.
Drain the old electrolyte into a sink and flush
away. Discard the shipment cartridge and
membrane.
4. Remove the cotton washer from the top of
the anode and discard.
5. Rinse the sensor head under a tap for 15
seconds, aiming the jet of water directly onto
the sensor head.
6. Do not dry the center electrode area, as the
gap between cathode and guard should be
left filled with water.

17
Installation
Note: During this next step, it is very important to
ensure your finger does not come into contact with the
cathode (golden surface) as it could leave greasy
deposits on the surface.
7. Take a new cotton washer from the recharge
kit. Hold it between thumb and forefinger and
position it on top of the anode as illustrated
right.
8. Place the recharge cartridge container on a
flat work surface and, keeping the container
upright to avoid spilling any of the electrolyte
inside, carefully unscrew the top.
9. Remove the packing component from the
center of the cartridge, making sure that the
O-ring on top of the cartridge remains in
place. If it comes away then replace it before
continuing.
10. If there are any visible bubbles in the
electrolyte, remove them using a stirring
motion with the packing component.
11. Hold the container steady between thumb
and forefinger of one hand.
12. Lower the sensor into the container until the
top of the anode is covered with electrolyte.
13. Leave for a few seconds to ensure the cotton
washer has fully absorbed some of the
electrolyte and that it is no longer dry.

18
Installation
14. Gently screw the sensor clockwise into the
replacement cartridge, applying minimum
pressure to avoid any damage to the screw
threads.
15. Continue turning until the cartridge is
attached to the sensor, and the sensor is
automatically released from the container.
16. The empty container, the screw top and
packing component can be discarded.
Note: It is normal that some of the electrolyte will
overflow from the replacement cartridge and into the
plastic container.
17. Rinse the sensor under a tap for about 5
seconds to remove any excess electrolyte,
then gently wipe with a soft tissue to ensure
all parts are completely dry.
18. Drain the overflow electrolyte from the
container into a sink and flush away.
19. Discard the used container.
