Overview
The 6100 Calorimeter has been designed to provide the user with:
• A moderately priced calorimeter for users who do not require the highest attainable precision.
• A traditional design calorimeter with removable oxygen bomb and bucket.
• A high speed calorimeter capable of performing up to 9 tests per hour when equipped with two bombs and buckets.
• A compact calorimeter requiring minimum laboratory bench space.
• A modern intuitive graphical user interface for ease of operation and training.
• A calorimeter with up to date digital hardware, software and communications capabilities.
<>Features
Outwardly, the 6100 Calorimeter appears to be the same as the 6200 Isoperibol Calorimeter, since both calorimeters are built into the same housing with the same keyboard and LCD display panel. But, there is one important difference: the 6100 Calorimeter does not have a temperature controlled jacketing system as required for isoperibol calorimetry.
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. And, with no permanent external connections (except a connection to an oxygen tank). The 6100 Calorimeter can be set up and made ready to operate in a few minutes, or it can be set aside when not in use.
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.
Benefits
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.
Multiple Language Options
Parr Model 6100 can be set to provide the programming options, operating menus, reports and error messages in the following choice of languages: English, French, and German.
