Using the method for measuring the differential pressure drop testing takes place by comparison with a reference sample.

During testing are both filled at the same pressure, then expects a stabilization phase, the end of which, the loss is measured by pressure difference which is generated between the two products.
The comparison between the two components, theoretically identical and with the same behavior, allows to reduce the testing time and especially the stabilization phase.
Furthermore the use of a differential pressure sensor allows to greatly increase the resolution and the sensitivity of the measurement.

Our sales engineers are at your disposal to help you choose the instrument that best suits your testing needs.
