The Sonde
The sonde head contains the electrodes, stirrer and temperature probe to carry out analysis.
It comes pre-assembled with the 4 electrodes and a Sample Analysis Beaker (SAB). The
electrodes are the WE1 (Working Electrode 1), WE2 (Working Electrode 2), R (Reference
Electrode) and C (Counter Electrode). The sonde has the electrode letter references
embossed onto it to ensure they are connected in the correct positions.
To fit an electrode, simply align the arrow on the electrode with the arrow on the sonde head
and push the electrode into its socket. A quiet double click should be heard. Gently pull on the
top of the black holder of the electrode to ensure it is fully connected.
To remove the electrodes, pull back the connector shroud with the arrow on and the
connector will pull off.
When attaching or removing the electrodes, be careful to avoid touching the stirrer.
The different Working Electrodes can be identified by the number of connecting pins and are
not interchangeable.
Electrode WE1 (6 pins) is to be fitted in position WE1.
Electrode WE2 (3 pins) is to be fitted in position WE2.
Do not mix up the electrodes as this can cause damage to the instrument.
The sonde can be assembled in one of two ways. Firstly, the short cable attached to the
Sonde can be connected directly to the instrument. It can them be attached to the clamp and
stand included in the kit and fitted inside the box. The second option is to fit the extension
cable between the sonde and the instrument. This allows the instrument to be used to collect
samples as well as analyse them.
