How Ambient Conditions Can Compromise Density Measurements in

Dec 13, 2016 · Absolute pressure uses a vacuum as reference, while relative pressure uses ambient pressure as reference. By being referenced to a vacuum, absolute pressure eliminates any inaccuracies that can be caused by changes in ambient pressure. The actual gas pressure is accurately measured, leading to correctly calculated gas density.
