Description:

A clear acrylic pressure box for application of consistent and even pressures from 0 to 20kPa (2.9psi)

In the normal orientation (as in photo), the samples are pressed so that the fluid passes through the perforated bottom plate of the device giving retention values at any required pressure level within the above range.

In the inverted position, rewet tests and absorption against pressure tests can be carried out and the fluid release can be observed through the perforated plate (top plate in this inverted position).

The device should be set over a conical drainer with the released fluids draining to a container set on a weighing scales. In this way the weight of released fluid at each increment of pressure can be recorded and charted.
