Vibrating wire pore water pressure gauge

Short Description:

The vibrating wire pore water pressure gauge is a measuring tool with secondary sealing performance. It is suitable for construction and installation by filling method. It can be buried in the foundation of hydraulic structures or other buildings for a long time to measure the pores in the foundation of structures ( Penetration) water pressure, and can simultaneously measure the temperature of the buried point.
