T
he proximate analysis of
a coal sample is a tedious
procedure involving sev-
eral separate weights and the
handling of data from several
sources as needed to calculate
Air-Dry Moisture,Total Moisture,
Volatile Matter, Fixed Carbon
and Ash. The 6750 Proximate
Interface is an advanced micro-
processor system, which sim-
plifies the collection, storage,
calculation, and reporting of
data needed during the proxi-
mate analysis of coal, coke and
related fuel.
Parr Instrument Company has
redesigned and significantly
enhanced the 6750 Proximate
Interface for proximate analysis,
including many new features
desired by users of the 1750
model. The new 6750 has the
ability to function as a Proxi-
mate Analyzer, an ADL Inter-
face, aTotal Moisture Interface
and a Balance Interface. As
compared to a PC, the unit is
compact, inexpensive and ro-
bust. The Interface weighs only
4.5 pounds and measures 11
inches wide, 5 inches tall, and
9 inches deep, saving precious
bench top space.
Numerous Capabilities
Operating seamlessly with cur-
rent laboratory equipment, the
6750 Proximate Interface will:
• Collect and store all
individual weights obtained
during the steps required to

determine moisture, volatile
matter, ash, BTU’s and
Sulfur
• Manage up to 1000 samples
• Coordinate and organize
data as it becomes available
• Calculate the resulting
proximate analysis for
each sample on any of
four reference bases:
As-Determined (AD), As-
Received (AR), Dry (DRY) or
Dry, Ash-Free (DAF)
• Convert and report BTU and
Sulfur values to selected
moisture reference bases
• Act as a remote Air Dry
Loss,Total Moisture
Interface or Balance
Interface
• Support data entry, storage
and reporting for Free
Swelling Index (FSI) and
Ash Fusion along with
the more traditional mass
loss or calorimetric based
measurements
• Print all results to a network
printer or a 1758 printer.
Data can also be transferred
to a central computer.
• Obtain a printout or report
of the proximate analysis,
BTU and Sulfur values for
each sample.
• Produce final or preliminary
reports at any time for any
sample ID.
