> <The W3 Pneumatic Piezometer is designed for accurately measuring pore water pressures in fully or partially saturated soil and rock.
The Pneumatic Piezometer tip comprises an integral porous element with a high quality diaphragm transducer, installed either down a borehole, by burying in fill or by pushing into shallow depths in soft soil.
Twin nylon tubes in a polythene sheath can connect the transducer to a terminal panel or to the portable readout unit directly.
The readout displays engineering-based units. Readings can be taken up to 500m from the tip.
