Airtightness Test

If the sampling pump is not airtight, measurements will not yield correct results. Before starting to measure, be sure to verify that the sampling pump is really airtight.

Note:

When you return the piston, please ease it back gradually (lightly holding on to it so it does not snap back in one thrust. Since there is a vacuum inside the cylinder, the handle tends to return rapidly). If it snaps back too hard, the impact can damage the pump causing it to malfunction.
