Equipment Description
The AccuPyc 1330 Pycnometer is an easy-to-use, fully-automatic gas displace-
ment pycnometer. Analyses are initiated with a few keystrokes. Once an analy-
sis is initiated, data are collected, calculations performed, and results
displayed without further operator intervention. The pycnometer may be oper-
ated in any of five languages: English, French, German, Italian, or Spanish.
The AccuPyc 1330 Pycnometer’s unique run precision feature increases the
precision of analysis results by reporting data from five consecutive runs that
are within a user-specified tolerance. This feature allows early termination of
analyses, thereby decreasing the number of runs needed for accurate results.
The AccuPyc 1330 Pycnometer, shown in the following illustration, contains
a keypad, a display area, and an analysis chamber (referred to as the cell
chamber). The pycnometer is controlled by commands entered through the
keypad. The operational status of the pycnometer can be continually moni-
tored on the display. The optional printer prints out complete analysis and
calibration results. A serial port is provided for electronic data transmission.

The AccuPyc 1330 Pycnometer determines density and volume by measuring
the pressure change of helium in a calibrated volume. It also reports the
chamber temperature at the end of the requested runs. The schematic dia-
gram, which is included above the keypad, indicates system status. The three
indicators show the current state of the fill, expansion, and vent valves. The
indicator is lit when a valve is open.
