Safety instructions
der such as splints, hay, straw etc. explode
when combusted! Always wet these materi-
als first! Highly flammable liquids with a low
vapour pressure (e.g. tetramethyl dihydrogen
disiloxane) must not directly touch the cotton
thread!
• Furthermore, toxic combustion residue in the
form of gases, ashes or condensation, for ex-
ample, is possible in the inner wall of the de-
composition vessel.
• When handling combustion samples, com-
bustion residue and auxiliary materials, please
observe the relevant safety regulations. The
following materials, for example, could pose a
risk:
– corrosive
– highly flammable
– explosive
– bacteriologically contaminated
– toxic
• Please observe the relevant regulations when
handling oxygen.
Warning: oxygen as a compressed gas is
oxidising; intensively aids combustion; can
react violently with flammable materials.
Do not use oil or grease!
• Caution - magnetism! Effects of the mag-
netic field have to be taken into account (e.g.
data storage media, cardiac pacemakers ...).
• When using stainless steel crucibles tho-
roughly check their condition after each expe-
riment. If the material gets thinner, the crucible
may catch fire and damage the decomposition
vessel. Crucibles must not be used for more
than 25 combustions for safety reasons.
• The decomposition vessel is manufactured
in accordance with the directive for pressure
equipment 97/23/EC.
This is indicated by the CE symbol with the ID
number of the notified body. The decompositi-
on vessel is a category III pressure device. The
decomposition vessel has undergone an EC
prototype test. The CE declaration of confor-
mity confirms that this decomposition vessel
corresponds to the pressure device described in
the EC prototype test certificate. The decompo-
sition vessel has undergone a pressure test
For your protection
• Read the operating instructions in full
before starting up and follow the safety
instructions.
• Keep the operating instructions in a place whe-
re they can be accessed by everyone.
• Ensure that only trained staff work with the ap-
pliance.
• Follow the safety instructions, guidelines,
occupational health and safety and acci-
dent prevention regulations.
• Wear your personal protective equipment
in accordance with the hazard category
of the medium to be processed.
• Calorimeter system C 200 may only be used to
determine the calorific value of solid and flu-
id materials. Only the appropriate original IKA
decomposition vessels may be used for this
purpose. For detailed information, please see
the operating instructions for the decompositi-
on vessels.
• The maximum extra energy added to the de-
composition vessel must not exceed 40,000 J
(select the test mass accordingly). The permit-
ted operating pressure of 230 bar must not be
exceeded. The maximum permitted operating
temperature must not exceed 50 °C.
• Do not overfill the decomposition vessel with
sample. Only fill the decomposition vessel with
oxygen to a maximum pressure of 40 bar.
Check the set pressure on the pressure reducer.
Perform a leakage test before each combustion
process (follow operating instructions for de-
composition vessel!).
• Some materials tend to explode when combus-
ted (e.g. due to formation of peroxide), which
could cause the decomposition vessel to crack.
• Standard decomposition vessels may not
be used for testing explosive samples.
• If the burning behaviour of a material is unk-
nown, it must be tested before combustion in
the decomposition vessel (risk of explosion). If
you are burning unknown samples, leave the
room or keep your distance from the calorime-
ter.
• Benzoic acid may only be combusted in its
pressed form! Flammable dust and powder
must be first pressed. Oven-dry dust and pow
• For the purposes of these operating instruc-
tions a technical expert is someone
1. who guarantees to conduct the tests properly
on the basis of his training, knowledge and ex-
perience gained through practical work,
2. who is sufficiently reliable,
3. who is not subject to any instructions in terms
of the test activity,
4. who has suitable test equipment if necessary,
5. who can provide appropriate proof of the re-
quirements listed in 1.
• National directives and laws must be observed
for operating pressure vessels!
• Anyone operating a pressure vessel must keep it
in a proper condition, operate it properly, super-
vise it, carry out the necessary maintenance and
repair work immediately and implement the sa-
fety measures required in the circumstances.
• Pressure vessels must not be used if they have
defects which could pose a risk to staff or third
parties. The pressure equipment directive can
be obtained from Carl Heymanns or Beuth pu-
blishers.
• The C 248 oxygen station must be set up at least
1.5 m far away from the calorimeter.
For protection of the equipment
• The voltage stated on the type plate must cor-
respond to the mains voltage.
• Removable parts must be refitted to the appli-
ance to prevent the infiltration of foreign ob-
jects, liquids etc.
• Protect the appliance and accessories from
bumps and impacts.
with test pressure of 330 bar and a leaka-
ge test with oxygen at 30 bar.
• Decomposition vessels are experiment autocla-
ves and must be tested by a technical expert
after each use.
Individual use is understood here to include a
series of experiments performed under roughly
the same conditions in terms of pressure and
temperature. Experiment autoclaves must be
operated in special chambers (C 2000, C 5000,
C 7000, C 200).
• The decomposition vessels must undergo re-
peated tests (internal tests and pressure tests)
performed by the technical expert. The fre-
quency of these tests is to be determined by
the operator on the basis of experience, type of
operation and the material used in the decom-
position vessel.
• The declaration of conformity becomes
invalid if mechanical modifications are
carried out to the experiment autoclaves
or if tightness can no longer be guaran-
teed as a result of major corrosion (e.g.
pitting by halogens).
• The threads on the body of the decomposition
vessel and the union nut are subject to conside-
rable stress in particular and must therefore be
checked regularly for wear.
• The condition and function of the seals must
be checked and ensured by way of a leakage
test (see operating instructions for decomposi-
tion vessel!).
• Only technical experts may perform pressure
tests and service work on the decomposition
vessel.
• We recommend that you send the decom-
position vessel to our factory for inspec-
tion, and if necessary, repair after 1000
tests or after one year or sooner depen-
ding on use.

and calculates the provisional result. The measu-
ring time is set at 14 minutes.
4.7 Filling the calorimeter for the first time
Before using the calorimeter for the first time
you must fill the outer vessel with tap water.
Destilled and/or deactveted water may not be
used!
To do this, pour two litres of tap water into the
filler of tank (see section 4.1) using the measu-
ring cup provided.
The water must first be maintained at a constant
temperature. To ensure accurate results, the initi-
al temperature must not fluctuate too much.
Water temperature 18 °C - 25 °C with an ac-
curacy of ±1 °C during a measurement series.
You must now pump the water out of the tank
into the outer vessel:

Pumping procedure is started
Keep an eye on the water by pulling the filler of
tank (see section 4.1) out the top.
When the overflow causes the water to run back
in the side of the tank, the outer vessel is full and
you must switch off the pump again by pressing
STOP OK (F2) once more.
You should change the water if it has been sitting
for a long time, see section 8.3.

Isoperibol
Calorimeter C 200 automatically performs the
measurement according to the standard for iso-
peribol calorimeters and calculates the provisional
result for you. The measurement takes approx. 17
minutes with excellent result reproducibility.
Manual
This is ”student mode”. You work according to
the standard for isoperibol / isothermal calorime-
ters. You read the temperature values off yourself
every minute, calculate the temperature drift be-
fore ignition, ignite and end the experiment by
pressing F1, calculate the temperature drift after
the temperature increase and calculate the result
itself.
Dynamic
Calorimeter C 200 performs the measurement
automatically and calculates the provisional re-
sult. The measuring time is reduced to approx. 8
minutes thanks to a dynamic correction process.
It is still possible, however, to meet the accuracy
specifications of the international standards.

4.10 Oxygen station C 248
The C 200 does not have an integrated oxygen
filling point for the decomposition vessel. You
can use oxygen station C 248 for filling. The C
248 oxygen station must be set up at least 1.5 m
far away from the calorimeter. For information on
how to operate and connect the oxygen station,
please see the accompanying operating instruc-
tions.
Operation:
• Place decomposition vessel C 5010 on the
marked position.
• Move the lever down and centre the de-
composition vessel below the fill head .
• Lock the lever in place.
• Fill the decomposition vessel for approx. 30
secs.
• Move the lever back to its original position.
4.8 Switching off the system
Standby mode
In order to switch off the calorimeter system, the
start screen must be displayed.
Press OFF (F1). The appliance will switch to
standby mode.
Switching off
Only switch the appliance off in standby mode.
To do this, press the ON/OFF switch (see sec-
tion 4.2) on the back of the appliance.
4.9 Coding decomposition vessels
You can use several decomposition vessels (max.
4) when working with calorimeter C 200. You
can code these to distinguish between them by
sticking the black coding strips into the special
slots on the decomposition vessels.

In many cases, however, not just the combus-
tion products referred to in the standards are
produced. In such cases the fuel sample and the
combustion products must be analysed to pro-
vide data for a revised calculation. The standard
calorific value is then calculated from the measu-
red calorific value and the analysis data. The heat
value Hu is the same as the calorific value, minus
the condensation energy of the water contained
in the fuel and formed through combustion. The
heat value is the more important parameter from
a technical point of view because in all major,
technical applications only the heat value can be
evaluated in terms of energy.
The complete bases of calculation for the calori-
fic and heat value can be found in the relevant
standards (e.g.: DIN 51 900; ASTM D 240; ASTM
D 5865..). They are also contained in the CalWin
calorimeter software.
5.2 Corrections
Due to the nature of the system a combustion
test does not just produce the combustion heat
of the sample, but also heat from external energy
(QExternal).
This can fluctuate considerably in relation to the
heat quantity of the fuel sample.
The combustion heat of the cotton thread which
ignites the sample and the electric ignition energy
would distort the measurement. This influence is
taken into account in the calculation by way of a
correction value.
5.1 Determining the calorific value
Combustion is carried out in a calorimeter under
specific conditions. The decomposition vessel is
filled with a weighed fuel sample, the fuel sample
is ignited and the temperature increase in the ca-
lorimeter system measured. The specific calorific
value of the sample is calculated as follows:
Ho = (C * DT - QExt1 - QExt2) / m (1)
m
Weight of fuel sample
C
Heat capacity (C-value) of calorimeter system
DT
Calculated temperature increase of water in inner
vessel of measuring cell
QExt1
Correction value for the heat energy generated
by the cotton thread as ignition aid
QExt2
Correction value for the heat energy from other
burning aids
The decomposition vessel is filled with pure oxy-
gen (99.95 %) to optimise the combustion pro-
cess. The pressure of the oxygen atmosphere in
the decomposition vessel is max. 30 bar. Formula
(1) for the calorific value of a material requires
that combustion takes place under specifically
defined conditions. The relevant standards are
based on the following assumptions:
• The temperature of the fuel and its combustion
products is 25 °C.
• The water contained in the fuel before combus-
tion and the water formed whilst combusting
the hydrogenous compounds of the fuel is in
fluid form after combustion.
• The atmospheric nitrogen has not oxidised.
• The gaseous products after combustion consist
of oxygen, nitrogen, carbon dioxide and sulp-
hur dioxide.
• Solid materials may form (e.g. ashes).
Calorimetric measurements

Failure to observe these instructions could re-
sult in damage to the decomposition vessel.
Exploding decomposition vessels present a risk
of serious injury or death. When working with
unknown substances, select very small weighted
samples at the start in order to determine the na-
tural energy.
Normally solid materials in powder form can be
combusted directly. Materials which com-
bust quickly (e.g. benzoic acid) must not
be burnt loose. These materials tend to splash
and there is therefore no guarantee of complete
combustion.
Furthermore, this can damage the inner
wall of the decomposition vessel.
IKA pelleting press C 21 and IKA analytical mill A
11 basic (see Accessories) are available for sample
preparation.
Materials which are dicult to burn (materials
with a high mineral content, low caloric materi-
als) can often only be fully combusted using IKA
acetobutyrate capsules C 10, IKA combustion
bags C 12 or IKA combustible crucible C 14 (see
Accessories). It is also possible to use liquid bur-
ning aids such as paran oil.
Before filling the capsule or the combustion bag
with the substance to be determined, weigh
them to calculate the extra external energy ad-
ded by the burning aid from the weight and the
calorific value. This must be taken into account
in QExternal2. You should keep the amount of
burning aid used to a minimum.
Most fluid substances can weighed out directly
into the crucible. Highly volatile substances are
poured into combustion capsules (IKA gelatine
capsules C 9 or IKA acetobutyrate capsules C 10,
see Accessories) and combusted together with
the capsules.
The burning aids (e.g. cotton thread) must also
fully combust. If there is any unburnt residue, the
test must be repeated.
When working with unknown substances, select
very small weighted samples at the start in order
to determine the natural energy. If you are bur-
ning unknown samples, leave the room or keep
your distance from the calorimeter.
After combustion the water produced is collec-
ted and the decomposition vessel is thoroughly
rinsed with distilled water. The water used for
rinsing and the solution produced are combined
and examined for their acidity. If the sulphur con-
tent of the fuel and the nitric acid correction are
known, it is not necessary to analyse the water.
Note: in all the automatic calculations an extra
100 J have already been included for the electric
ignition energy. This value cannot be set.
Materials which are dicult to ignite or combust
are combusted together with a burning aid. The
burning aid is first weighed and then put into
the crucible with the sample. The additional heat
quantity can be determined from the weight of
the burning aid and its known specific calorific
value. You must correct the test result by this heat
quantity.
IKA- combustible crucible C 14 is a combustible
crucible, which can be used instead of a standard
crucible. The combustible crucible burns without
leaving any residue whatsoever. When using a
combustible crucible you do not need an extra
cotton thread. The crucible is placed directly on
the permanent ignition wire in the decompositi-
on vessel and ignited.
The cleanliness of the material used in the com-
bustible crucible prevents chemical contaminati-
on of the sample (no blank values).
Decomposition vessels, in which the combustible
crucible is used, must be fitted with an extra part
(support C 5010.4, see Accessories). The sample
is weighed out into the combustible crucible as
normal. In most cases no additional burning aid
is required because the combustible crucible itself
serves as a burning aid.
Virtually all of the materials to be studied contain
sulphur and nitrogen. Under the conditions in ca-
lorimetric measurements, sulphur and nitrogen
combust to SO2, SO3 and NOx. Together with
the water from combustion and moisture, sulp-
huric and nitric acid as well as heat of solution
are produced. In order to obtain the standard ca-
lorific value, the influence of the heat of solution
on the calorific value is corrected. The calculation
formulae depend on the standard used. These
are not taken into account in the calculation for
C 200. Use IKA's CalWin software for this.
5.3 Information about the sample
FIt is essential that the sample fully combusts
to ensure correct determination of the calorific
value. After each experiment check the crucible
and all the solid residue for signs of incomplete
combustion.
As a rule the weighted sample must be se-
lected in such a way that the temperature
increase during the measurement is below 4 K
and comes close to the temperature increase
of the calibration (max. extra energy: 40,000 J).
The system must be calibrated in every work
mode used.
If a calorimeter is operated with several de-
composition vessels, you will need to deter-
mine the heat capacity of the system for each
decomposition vessel.
Ensure that calibration is carried out under the
same conditions as the subsequent tests. If sub-
stances are used in the decomposition vessel in
combustion tests (e.g. distilled water or solu-
tions), you must use exactly the same amount of
this substance for calibration.
For more detailed information on calibration, ple-
ase see the relevant standards.
6.1 Decomposition vessel C 5010
If several decomposition vessels are used,
their individual parts must not be interchan-
ged (see Stamping individual parts).
To prolong the life of wearing parts (o-rings,
seals, etc.) we recommend that you always
work with a water trap.
5.4 Calibration
The calorimeter system must be calibrated before
accurate measurements are possible. This is done
by combusting tablets made of certified benzoic
acid (see Accessories) with a known calorific va-
lue. The heat quantity required to raise the tem-
perature of the calorimeter system by one Kelvin
is used to determine the heat capacity of the so-
called "C-value" of the system. For this calculati-
on the formula (1) (see section 5.1) is adapted:
C = (Ho * m + QExt1 + QExt2) / DT (2)
This value is used for determining the following
calorific values.
The heat capacity is determined by the measu-
ring cell and the decomposition vessel. It has a
significant influence on the calorific value to be
calculated and must be redetermined in particular
when using for the first time, after servicing and
when parts are replaced. A monthly control mea-
surement is recommended.
The term "measurements" below refers to both
the measurements to calibrate the calorimeter
system (calibration measurements) and the actual
measurements for determining the calorific value.
The difference lies in the calculation (cf. section
5, formulae (1) and (2)), whereas preparation and
performance are virtually identical.
Exact measurements are only possible when the
individual test steps are carried out carefully.
You must therefore follow the exact proce-
dure described in section 1 "For your safe-
ty” and in the following sections
Please also see section 5 "Calorimetric measure-
ments”.
Failure to observe these instructions could re-
sult in damage to the decomposition vessel.
Damaged decomposition vessels could crack!
Follow the operating instructions for the de-
composition vessel!

6.2 Preparing the decomposition vessel
Prepare the decomposition vessel as follows:
Unscrew the union nut and remove the cover
using the handle.
Attach a cotton thread to the centre of the
ignition wire using a loop.
Weigh out the substance directly into the
crucible with an accuracy of 0.1 mg. Note the
weight or enter directly into the calorimeter. (See
section 6.3 "Preparing the measurement").
Insert the crucible into the crucible holder.
If necessary put some distilled water or a solution
into the decomposition vessel.
See section 5.3 "Information about the samp-
le" and section 1 "Safety precautions”.
Using tweezers, align the cotton thread so that
it hangs inside the crucible and is immersed in the
sample. This will ensure that the burning thread
ignites the sample during the ignition process.
Attention! Place the cover onto the lower
section and push down until it presses against the
stop piece in the lower section. Place the union
nut onto the lower section and tighten by hand.

Press OK (F1) to apply your entries.
6.4 Performing the measurement
Once you have done all the necessary prepa-
ratory work as described above, the message
”Storage filled?” (Tank filled?) will appear. Check
that the tank is filled with water maintained at
a constant temperature and confirm by pressing
CONTINUE (F1).
The message appears “Vessel safe locked?“
Make sure the fact that the the decomposition
vessel is duly locked and confirms you this with
OK (F1).
After in each case 1000 ignitions of an decompo-
sition vessel you are with the message “Vessel x :
1000 ignitions!” pointed out that this decompo-
sition vessel reached one point of maintenance
time and must be submitted of a security exami-
nation.
Confirming these references by you successively
OK(F1) and OK(F2) press.
This reference does not relieve you of the obliga-
tion to already constandly examine decompositi-
on vessel also before on wear and accomplish the
safety examination if neccessary.
The message appears “Close the cover“.
After the measurement open the cover to au-
tomatically empty the inner vessel. Remove the
decomposition vessel and the ignition adaptor. To
release tension in the decomposition vessel use
venting button under a fume hood or venting
station C 5030 available in our accessories range.
See also section 1 "Safety precautions".
Open the decomposition vessel and check the
crucible for signs of incomplete combustion. If
combustion is incomplete, discard the test result.
Repeat the test.
6.5 Cleaning the decomposition vessel
If you suspect that the combustion sample,
the combustion gases produced or the com-
bustion residue could be harmful to health,
wear personal protective equipment (e.g.
protective gloves, breathing masks) when
handling these materials. Harmful or polluting
combustion residue must be disposed of as
hazardous waste. Express reference is made
to the applicable regulations.
In order to obtain accurate measurements it is
essential that the decomposition vessel is clean
and dry. Impurities alter the heat capacity of the
decomposition vessel and thus cause inaccurate
measuring results. It is important to thoroughly
clean the inner walls of the vessel, the internal
fittings (brackets, electrodes etc.) and the com-
bustion crucible (inside and out!) after each com-
bustion test.
In most cases, you will only need to remove con-
densate from the inner walls of the vessel and the
internal fittings. It is sucient to thoroughly wipe
the parts with an absorbent, non-fibrous cloth. If
the decomposition vessel cannot be cleaned in
the above way (e.g. due to baking, pitting, cor-
rosion etc.), please contact the Technical Service.
a) The measurement process is fully automatic
for automatic measuring procedures (isoperibol,
dynamic and time-controlled, see section 4.6).
The result will appear once the measuring pro-
cess is complete.
b) With the manual measuring procedure the
user decides when ignition is to take place and
when the measurement is complete.
To start ignition press IGNITE (F1)
Press the same key END (F1) again to end the
measurement
In the case of manual ignition / completion, "Pre-
paring to ignite" or „Preparing to complete" will
appear in the status line. Ignition/completion is
only finished when this display disappears (max.
60 sec.).

7.1 Operation
This menu allows you to directly control and test
various actions and statuses of the calorimeter
without performing a measurement. There are
also menu items which can be used to start up
and shut down the appliance. The service menu
can only be run if the calorimeter displays the
start screen.
Perform the desired action using:
MENU (F3)
UP/DOWN (F2) to "Service"
OK (F1)
There are now eight actions to choose from

Select the desired action with UP/DOWN (F2 )
OK (F1) starts the action
OK (F1) stops the action again
Service menu Reset
This menu item allows you to restore the default
settings.
Reinit
This menu item allows you to reinitialise the
A / D converter.
There is also a filter in the filler. This prevents dirt
in the storage container. If the filter is dirty, remo-
ve the entire filler and clean the filter (see section
4.1, ).
8.3 Micro filter
In the back plate of the equipment is additionally
a micro filter. If the micro filter is dirty, the water
flow in the equipment is reduced. Thus the water
filling time of the inner vessel extends. Thereby
if the upper time limiting is exceeded by 120 se-
conds, the system indicates the disturbance and
breaks the measurement off.
Pump
Switch the pump on with this menu item. The
outer vessel will be filled and rinsed (see also sec-
tion 4.7).
Requirement:
Check that there is water in the tank.
Empty outer vessel
This menu item allows you to empty the outer
vessel.
Note:
Shut-down, completely empty appliance.
Requirement:
The emptying hose must be locked in place in
plug-in coupling (section 4.2).
In order to ensure trouble-free operation over a
long period of time, it is important to carry out
the following maintenance work to the calorime-
ter system.
Disconnect main plug prior
to cleaning!
8.1 Inner vessel filler
Remove the filter element from the inner vessel
and clean the inner vessel filter in clear water or
an ultrasonic bath if there is any dirt visible. Also
clean the inner vessel, by re-moving the positio-
ning mount for the decomposition vessel. Place
the filter back on the inner vessel connector after
cleaning.
Operation without the filter element causes dirt
in the valves and thus appliance failure.
8.2 Filler
Cleaning and maintenance

28 29
8.4 Maintaining the water circulation
In the case of discontinuous use with tap water
(single measurements with long gaps) a stabiliser
must be added to the water circulation to prevent
the formation of algae.
Add approx. 4 ml IKA-Aqua-Pro C 5003.1 to the
tank (see Accessories).
Switch the pump on via the service menu (sec-
tion “Pump“). Switch the pump off again after
30 - 60 s.
You can also add the 4 ml Aqua-Pro to the water
maintained at a constant temperature in the last
measurement (before long gaps in measuring).
If the appliance is not going to be in opera-
tion for a long period of time, it is advisable
to completely empty the calorimeter's water
circulation.
The water must be drained out before trans-
portation.
Empty the outer vessel via the service menu (sec-
tion 7.2 “Outer vessel“). The emptying hose must
be locked in place in the plug-in coupling (sec-
tion 4.2).
Empty the tank by locking the emptying hose in
place in the plug-in coupling (section 4.2). The
tank will empty automatically.
Press the locking knob on the plug-in coupling 
to remove the hose.
8.5 Decomposition vessels
Please see the operating instructions for
C 5010 for information on decomposition
vessel maintenance!
8.6 Cleaning information
