Design Features
The modualar design of the rigs
The 6100 Calorimeter is intended for the user who wants
a modern calorimeter with the convenient automatic features provided in the
6200 Calorimeter and whose precision requirements can be met with a static
system without isoperibol control. Or, for users whose work load is small or
intermittent, making it preferable to purchase a lower cost model. To meet
these criteria, the temperature controlled water jacket and its accessories
have been removed from the 6200 Calorimeter and replaced in the 6100 with a
static air jacket around the bucket chamber, comparable to the arrangement used
in the 1341 Plain Calorimeter. This eliminates all water and water connections,
resulting in a significant saving in cost.
All sensors and controls in the 6100 Calorimeter are
built into a single, compact cabinet to provide a self-contained operating unit
consisting of:
- An 1108 oxygen bomb with an oval bucket which fits
into the insulating water jacket.
- A built-in semi-automatic system for charging the
bomb with oxygen.
- A high precision electronic thermometer.
- A bright, color, touch screen display for data entry
and operation control.
- Special communication ports for printer, computer and
network (LAN) connections.
- Removable compact flash memory card slot for simple
program updates and test report archiving.
Good Repeatability
To obtain the best precision with an uncontrolled
jacket, the 6100 Calorimeter has a temperature monitoring capability built into
the jacket. This allows the calorimeter to measure the actual jacket
temperature and apply the appropriate heat leak corrections in real time. While
not equal to an isolating water jacket, the 6100 method offers a significant
improvement over the traditional static jacket and makes it possible to obtain
reasonable precision without the long pre- and post-periods normally required
for static jacket calorimetry. It also makes it possible to use the Parr
Dynamic Method for rapid testing.
As with all static jacket calorimeters, best results
will be obtained when the calorimeter is operated in a location where it is not
subject to drafts or fluctuating air temperature, preferable in a
temperature-controlled room. It may require more frequent standardization if
the ambient temperature changes during the day or from day to day. With these
constrictions under control, standard deviations in a series of tests with a
uniform sample, such as benzoic acid, should not exceed 0.2 percent. The
precision obtainable will be more than adequate for most waste screening and
teaching applications. .
A Self-Contained Operating Unit
The 6100 Calorimeter is a compact operating unit that
uses the same 1108 oxygen bomb and oval bucket furnished with the 6200 or with
the 1266 and 1356 previous models. It also has the same automatic oxygen
filling system and high precision electronic thermometer used in the 6200
Calorimeter. There is a touch-panel keyboard for data entry and a color LCD
display for operator prompts, status indication, data verification and report
views. All steps in the test procedure are managed by a microprocessor control
system programmed to operate the calorimeter in either the conventional
equilibrium mode or in a faster dynamic mode. All data is handled automatically
by a dedicated microcomputer.
Printed Reports
An optional 1757 Printer can be furnished with each 6100
Calorimeter to produce a permanent record of all activity within the
calorimeter.
