13.
Place approx. 2.5 cm quartz wool in the inlet of the quartz tube and push the
quartz wool towards the end of the tube with a hook.

Servicing the combined electrode
NOTICE
The combined electrode can be destroyed by detergents or abrasives.
For cleaning the combined electrode may only be rinsed with Ethanol or distilled wa-
ter. The use of abrasive detergents or abrasives is prohibited.
Drying of electrolyte on the combined electrode can cause an irreversible reduction of
its sensitivity or damage the electrode. Therefore, make sure that the electrolyte never
dries on the combined electrode.
For brief interruptions of operation (one day to the next):
Store the electrode in the electrolyte solution.
For decommissioning over several days:
Rinse the combined electrode with distilled water and Ethanol. Immerse the elec-
trode in Ethanol over-night, stirred with a magnetic stirrer. Then wipe the com-
bined electrode with cellulose and store it dry.
NOTICE
The combined electrode consists of ceramic materials and is particularly sensitive near
the fused electrodes.
Handle the combined electrode with great care! As a wearing part it is not covered by
the warranty!
Pulling the combined electrode out of the cover of the measuring cell and connecting it
to the measuring gas can result in great mechanical stress if handled incorrectly and
lead to its electrical connection becoming fractured.
