he 1341 Plain Jacket Calorimeter
is the current version of the static
jacket, oxygen bomb calorimeter that
Professor Parr developed over 100 years
ago. It is a reliable calorimeter that can
be used for the same broad range of solid
and liquid combustible samples as the
6000 Series Calorimeters. Its modest cost
and simple design make the model suit-
able for low throughput and minimal
precision work such as sample screening
and student instruction.
Static Jacket
Although commonly called a plain calo-
rimeter because of its simple design, tech-
nically this is a static jacket instrument
which operates at or near room tempera-
ture with no provision for controlling the
jacket temperature. Compensation for
any heat loss (or gain) during a test is
made by applying a correction computed
from heat leak measurements taken
before or after each test. Good repeat-
ability can be obtained with the 1341
Calorimeter provided that the temp-
erature rise and heat leak corrections
are measured and applied carefully.
Laboratory Requirements
The calorimeter requires a source of
99.5% oxygen and deionized water for
operation.
1341 Plain Calorimeter
The 1341 Plain Calorimeter includes
the following components:
• 1341 Calorimeter
• Oxygen Bomb
• Oval Bucket
• Oxygen Fill Connection
• 6775 Digital Thermometer
• 6008 Bomb Maintenance Kit
• 2901 Ignition Unit
6775/6775A Digital Thermometers
The 6775
Digital
Thermometer
provides digi-
tal precision
and reliability
for tempera-
ture measure-
ments. The thermometer has a working
range of 10 to 40 °C and a resolution of
0.001 °C. The readout is displayed on
a clear LCD screen with a free-running
timer. In addition to displaying tempera-
ture, the thermometer includes a timer
that can be used to manually record the
time intervals of specific temperature
readings. The 6775A Data Logging Dual
Channel Digital Thermometer comes
equipped with a serial RS-232C interface.
This interface is used to configure the
thermometer for advanced operation such
as logging temperatures at a user speci-
fied time interval. These thermometers
use high capacity lithium batteries which
provide approximately 200 hours of oper-
ation. Designed for use with the Parr 1341
Plain Jacket Calorimeter, the 6775/6775A
is a replacement for the 1604 and 1623
liquid-in-glass thermometers.
