Model EPP-30V
EPP-30V is a vibrating wire piezometer used to measure pore water pressure in soil, earth/rockfills, foundations and concrete structures. EPP-30V is of stainless
steel construction and hermetically sealed under a vacuum of 0.001 Torr. Each sensor has built-in thermistor for temperature measurement and surge arrestor for
lightning protection. A glass to metal seal solder pin connector is provided for easy cable connection. The piezometers are very suitable for use as multi-level
piezometers mounted at different levels in the borehole using the grout-in technique.
