Correct

Incorrect

Hold the electrode from the top and pull the

electrode straight upwards out of the cover.

Do not pull and jolt the lateral connection

sleeve for the electrical connections. The con-
nections in the sleeve will break (not visible

from outside)!

Correct

Incorrect

Only push the measuring gas hose approx.

1 cm onto the electrode. This ensures gas
tightness.

If you push the hose too far onto the electrode,

it will get stuck on the electrode. When pulling
off the hose, the electrode might break!

7.3.4

Servicing the measuring cells

Since the introduction of hot reaction gases during the measurements causes electro-
lyte components to evaporate, it is recommended to change the electrolyte solution

daily:
1.

Remove the used electrolyte.

First rinse the measuring cell and magnetic stirring rod with distilled water, then

with Ethanol.

Carefully wipe the measuring cell and magnetic stirring rod with cellulose to re-
move any silver chloride deposits.

Refill the measuring cell with electrolyte (

see section "Preparing the measuring

cell" p. 87).
