Filling and Purging Pressure
Determining the maximum pressures to use.
The maximum operating pressure of the AccuPyc
III is 19.85 psig, with the standard being 19.5 psig. The instrument may be damaged if the gas supply is
above 22 psig.
A filling pressure of 19.5 psig may compress some samples, resulting in a decrease in
volume or increase in density. The operating pressures should be reduced to
obtain results that do not impact volume or density results.
