VWP type vibrating string permeameterDetailed product description：

The VWP vibrating string type pressure gauge is suitable for long-term burial in hydraulic structures or other concrete structures and soil, measuring the permeability (pore) water pressure inside the structure or soil, and can simultaneously measure the temperature at the burial point. The installation of matching accessories for the pressure gauge can be used in pressure measuring pipelines and foundation drilling.
