This tests purpose is to get the air content of a sample of concrete using a pressure meter. In the meter you have a known volume of air at a known pressure in a sealed air pot with an unknown volume of air being contained inside the sample of wet concrete. You set it to the percentage of air (your initial pressure) where the pressure is equalized inside the chamber, fill it with concrete and water so that the only air left is the air inside the concrete, and then release the pressure inside of
