Measurement made easy
1 Introduction
These procedures must be carried out by a trained
technician.

3 Safety
WARNING
These procedures must be carried out by a trained
technician.
ELECTRICAL
• Isolate all high voltage supplies to the transmitter before
performing replacement procedures.
• The wet-section is vulnerable to electrostatic damage.
Wear an anti-static strap or dismantle the wet-section on
an anti-static workbench.
• Ensure all electrical connections are kept dry at all times.
GENERAL
• Shut off the external sample supply to the wet-section
and drain the flowcell – refer to the wet-section Operating
instructions (OI/ADS550-EN) for flowcell drainage
options.
• When a procedure is complete, restore power to the
transmitter and sample to the wet-section at the correct
flow rate.
• If necessary, calibrate the wet-section – refer to the wet-
section Operating Instructions (OI/ADS550-EN) for
calibration instructions.
• Perform general cleaning of the wet-section using a damp
cloth only – mild detergent can be used as a cleaning aid.
Do not use Acetone or any organic solvents.
• Dispose of the old components in accordance with the
guidelines contained in the Operating instructions
(OI/ADS550-EN).

WARNING
Dispose of the old components in accordance with the
guidelines contained in the Operating instructions
(OI/ADS550-EN).

Referring to Figure 2:
1 Disconnect (red) sensor connector A.
2 Unscrew clamping screw Band withdraw the sensor
assembly from flowcell body C.
3 Carefully unscrew connector nut Gfrom sensor Dand
withdraw connector body E.
4 Remove and discard O-rings Fand H.

…6 Replacing the dissolved oxygen sensor
Fitting a new dissolved oxygen sensor assembly
CAUTION
• Only install the sensor immediately prior to use. The
sensor has a limited shelf life and, ideally, should NOT be
stored longer than 6 months. Store under cool conditions.
• Take special care to line up the two pins in the sensor with
their respective sockets before making the connection
and tightening.
• Take care not to damage the delicate membrane on the
face of the sensor.
• Ensure that the mating surfaces (carrying the electrical
connection) of the sensor and connector body are clean
and completely dry.
• Do not overtighten the clamping screw.
1 Remove the top from the new sensor container.
2 Unscrew the protective cap from the rear of the sensor.
Referring to Figure 3:
3 Fit the smaller of the 2 new O-rings A(¾ in. ID) onto the
connector body B.
4 Locate sensor Conto connector body B, ensuring the pins
and sockets are engaged correctly and tighten connector
nut D onto sensor C.
5 Insert the complete assembly into flowcell E, ensuring the
larger of the 2 new O-rings F ( in. ID) is fitted.
6 Screw in clamping screw Gusing finger-pressure only to
secure the dissolved oxygen sensor assembly in the flowcell
body.
7 Push (red) sensor connector H onto sensor connector block I
firmly and tighten ONE TURN clockwise.
