6 Calorimeter calibration
General features
The calorimeter's calibration is done in order to determine the termic capacity and the
coefficient of thermical loses. These characteristics are determined through zinc oxid cal-
cined dissolution in the acid mixture and by measuring calorimeter's temperatures with
prefixed range.
The acid mixture temperature must be planed so that after the dissolution reaction, the
calorimeter's temperature is at least 0,5°C below the ambient's temperature. When it's
used a bath of water, the bath's temperature is considered like the calorimeter's ambient
temperature.
Procedure
Measure a quantity of acid mixture in mass or volume, at ±0.2% so that the liquid's level
is about 2 cm below the calorimeter's cover. Introduce the acid mixture in the fIask. Just
before the determination of thermic capacity, to lime zinc oxide at (950 ± 25) °C for 5 min
maximum, then let it chill in a desiccator until the ambient temperature is reached.
The zinc oxide quantity to use, weighed at ±0,0001g is requested in order to satisfy the
following equation:
Acid mixture mass/zinc oxide 's mass = 60±1
Perform the following procedure:
1- preliminary period
Mix the acid mixture for a period between 40 and 50 min.

Calorimeter
1.0235
12
2- pre period
When the speed's increase is constant, start to count times using a chronometer and
register the starting temperature T -15.
3- Specimen's introduction
Register the temperature after 15 min, T0, and immediately add the zinc oxid specimens
to the acid mixture, not using more than one min time.
4- dissolution period
Mix the mixture for 30 min, afterward the dissolution is considered complete, then register
the temperature T30.
Register the ambient temperature, Ta. If the difference between Taand T30 is lower than
0,5 °C, repeat the test.
5- Following post period
Register the final temperature T45 after other 15 min
In order to reduce reading mistakes, determine the temperatures T-15 T30 and T45 as a
result of five different readings registered with one minute break in the period of time of
two min before and two min after the established time, Ti( i.e. T1-2, Ti-1, T1, Ti+2 ). Deter-
mine the value of T0extrapolating the temperature's function respect at the break time
between T- 4 and T-15 . If the value extrapolated is different from the reading T0with the
value extrapolated.
If more than one zinc oxide trace is found on the funnel's point and on the cover when the
calorimeter is opened, repeat the calibration.
Note: The temperature's lectures begin17 min before introducing specimens of zinc oxide
and the last reading will be 47 min after its introduction. The total calibration duration is
64 min.
7 BECKMAN thermometer operation
A Beckman thermometer is a differential thermometer displaying a temperature change
in a range comprised in the absolute range of the thermometer itself.
It is important to point out that the Beckman thermometer does not display an absolute
temperature but only a variation in comparison to a reference value. This value must be
defined by using a reference thermometer that will also be used to calibrate the Beckman
thermometer.
The Beckman thermometer must be set-up and calibrated each time we change the ref-
erence temperature tram which a variation must be measured.
The thermometer is composed of the following main parts:
Bulb
Differential range
Absolute range

Calorimeter
1.0235
13
Reservoir-coil
Bulb (A) allows to detect a temperature .
Differential range (B) allows to read the temperature change detected by the bulb
Absolute range (C) allows to read the reference temperature at which the thermometer
has been calibrated
Reservoir-coil (D) contains, after the calibration, the mercury exceeding the reference
point
Before using the Beckman thermometer, the mercury must be correctly compacted and
the thermometer calibrated.
7.1 Compaction of Mercury
The thermometer must be set-up so that the mercury is positioned as per Pic. 1
The mercury must be as shown (in the capillary), must be continuous from the bulb to the
reservoir-coil and must not present interruptions
Very likely a brand new thermometer will be received with a different mercury position,
therefore the first operation to carry out is to compact mercury and restore its cohesion.
A right position-cohesion can be found only through a correct and careful manipulation of
the thermometer, this operation requires patience and same experience and familiarity
with this product typology.
We must tilt the thermometer to let the mercury reach the above mentioned correct posi-
tion by gravity. This operation may require more than one trial, considering that the gravity
may also cause interruptions of the mercury's cohesion in the capillary.
Interruptions in the mercury cohesion do not mean that the thermometer is damaged,
since mercury is contained in a vacuum capillary; a correct cohesion will be obtained
through a patient a accurate manipulation.
We recommend the following procedure:
1) Position the thermometer vertically with the bulb on top (Pic. A), so that the mercury
leaves the bulb, goes through the capillary and reaches the rest of the mercury con-
tained in the reservoir-coil
2) Leave the thermometer in this position until the mercury has achieved a complete co-
hesion through the capillary and up to the reservoir-coil
3) Slowly rotate thermometer to a tilted position with the bulb downwards (Pic. B) an
place it in a firm position on a support. In such a position the mercury will flow down by
gravity from the reservoir-coil to achieve a correct positioning as per Pic. 1
In such a position the mercury in the reservoir-coil will display the current temperature
detected by the bulb, in comparison with the absolute range.
Remark
If, during the above described sequence, the mercury loses cohesion
in the capillary, you will need to repeat the operation until the expected
cohesion result is achieved.

Calorimeter
1.0235
14
7.2 Thermometer calibration
To set the mercury in the right way and allow the thermometer to measure and display
the temperature change, in comparison with the reference temperature, we recommend
proceeding this way:
1) Supply to the bulb with a temperature of 2 - 3°C higher than the reference temperature
from which the variation must be measured
To do this and to measure temperature you need a good precision referencethermometer
2) Let temperature settle so that the exceeding mercury flows up to the reservoir-coil
3) Supply the bulb with the reference temperature (still measured using the precision
thermometer) from which the variation will then be measured. In this way the mercury in
the capillary will abandon the reservoir-coil, flowing down to the differential range
4) Mark the correct position of the mercury in the capillary in comparison with the differ-
ential range. This position corresponds to the temperature measured by the reference
thermometer All variations read on the differential range correspond to a temperature
change of the bulb
7.3 Decommissioning
Should it be decided that the machine is to be no Ionger used so dispose of according to
the standards in force.
