15 Connector plug 16 Measuring vessel cover (6.0913.130)
Contains integrated conductivity measuring
cell.
17 PTFE tube (6.1819.080)
For supplying the air to the measuring solu-
tion.
18 Electrode
19 Protection ring 20 Glass measuring vessel (6.1428.030)
Proceed as follows to mount the measuring and reaction vessel:
1 Mount the measuring vessel cover
￭ Insert the PTFE tube (5- 17 ) from above into the opening In (5- 13 )
of the measuring vessel cover.
￭ Screw the tubing adapter M8 / olive (5- 11 ) into the opening In of
the measuring vessel cover.
￭ Place the measuring vessel cover (5- 16 ) on the measuring vessel
(5- 20 ).
2 Mount the reaction vessel cover
￭ Insert the air tube (5- 5 ) from below into the connection (5- 7 ) of the
reaction vessel cover.
￭ Place the O-ring (5- 6 ) over the upper end of the air tube.
￭ Screw the thread adapter M8 / M6 (5- 3 ) gently into the connection
(5- 7 ) and, at the same time, press the air tube against the
thread adapter M8 / M6.
￭ Now fix the air tube onto the reaction vessel cover by firmly pulling
the thread adapter M8 / M6.
￭ If determinations are carried out with highly foaming samples,
clamp the foam barrier (5-
9 ) onto the air tube.
￭ Place the reaction vessel cover on the reaction vessel.
Warning
The foam barrier can melt if it projects too deeply into the heating block.
Ensure that the foam barrier (5- 9 ) is at least 7 cm above the base of the
reaction vessel (5- 10 ).
