Pentapycnometer & Ultrapycnometer 1000
Feature Benefits

Automatic Functions:	Operating simplicity is achieved by user prompts or instructions which are automatically presented on the alphanumeric display. Measurements and printout of results are totally automatic. Continuous self-diagnostics monitor and signal fault conditions that may arise. The transducer is reset to zero prior to each run. Front panel LED's display the operational status at all times.
Sample Identification:	In the analysis parameters, up to a six-digit number may be added to uniquely identify the sample.
Temperature Readout:	Sample temperature is displayed and printed to ą0.1°C. This feature is important for (a) verifying operation at the calibration point or, (b) making corrections when analyzing larger quantities of materials whose density varies significantly with temperature.
Target Pressure:	The measurement of pressure-deformable cellular foams (insulation) is made possible by this feature. A user can conveniently reduce the target pressure typically from around 18 psi to as low as 0.5 psi. A special version, the UltraFoam™ pycnometer, automatically scans for the optimum pressure and performs calculations of open and closed cell content with or without ASTM correction for cut cells.
Sample Purge:	Before analysis, samples are automatically conditioned to remove contaminants and trapped air. The user has a choice to purge by a continuous flow to prevent elutriation (blowing out) of fine particles, or by a pulse mode more suitable for coarse powders or bulk solids. The Pentapycnometer purges all five stations simultaneously thus requiring no more time than for a single analysis.
Repeat Run Mode:	This feature eliminates the need to reenter the same set of analysis parameters prior to each run. It allows one to quickly change sample weight and sample ID, or simply to rerun a sample by a double keystroke.
Useful Statistics:	For three or more averaged measurements the % coefficient of variance and the standard deviation of the Volume and the Density are printed out. This allows a relative comparison of samples from run-to-run and a precise assessment of the absolute variation of the sample being measure.
NIST Traceability:	Pycnometer volume calibration spheres can be provided with a formal Report of Calibration from the National Institute of Standards and Technology.
Computer Software:	To capture printed output, automatic pycnometers are available with PC software that provides disk storage (ASCII format) of data along with all user entered information. Archived files can be recalled for review, printing and importation to other programs.
