Decomposition vessels C 7010 and C 7012 are required for determi-
nation of the gross calorific value in the IKA C 7000 calorimeter. The
are equipped as described in DIN 51 900 T1 5.1. In addition, these
decomposition vessels have integrated temperature sensors which
allow the temperature to be maesured directly in the vessel.
These decomposition vessels are pressure containers in which com-
bustion may be carried out with oxygen atmospheres. The pressure
contain consist of the three pressure-bearing parts which are corre-
spondingly marked. They include:
• bottom part • cover • cap screw
The device also features built-in components for electric ignition and
or holding the combustion crucible (in accordance with DIN 51 900 T1
5.6): These include:
• electrode • dish holder
The electrode also assumes the function of the non-returnable valve.
The valve is used to both fill the vessel with oxygen (C48) and to
empty it. The insides of the decomposition vessel are protected by
employments from suitable material.
For easy handling, the bottom part of the decomposition vessel is
provided with a sealing (item 18) on which the device can also be
set up on to laboratory tables. The integrated board (item 20)
which is used for transmission of the temperature signal and for
recognition of the decomposition vessel makes it possible to posi-
tion the decomposition vessel wherever required.
Please unpack the decomposition vessel carefully and check it for
damage. It is important that any transport damage is detected
when the vessel is unpacked. If necessary, and inventory of the
damage should be made immediately (postal service, railway, hou-
lage company).

When working with the C 7000FZ calorimeter system, a maximum of
8 decomposition vessels can be used. This is made possible through
coding of the decomposition vessel from No. 0 to No. 7.
The calorimeter automatically recognizes the decomposition ves-
sel that is presently being used for a measurement.
Coding is carried out by separating the conductor line on the prin-
ted circuit board (item 20) located in the bottom part of the decom-
position vessel. the conductorlines are marked with I, II and III.
(see Figure 1)
It is utmost impor-
tance that the thick
conductor lines are
not damaged when
the thin conductor
lines are separated.
It is advisable to use
a sharp knife in order
to cut the thin con-
ductor lines at a
distan-ce of 2 mm.
The piece in bet-
ween is then remo-
ved.
