The wet wet differential pressure transducer is predominantly used in Method B (HKUST method), of the GDS UNSAT testing process. Here the transducer is calibrated to directly measure sample volume change by comparing head of water in an inner cell and reference tube.

The transducer can also be used as a standalone device and calibrated in differential pressure (kPa). For more information on our unsaturated testing methods click here. Need advice choosing the right transducer, view our options table here.
