Description
Model: EDS-64U-D
The EDS-64U-D is a single-point borehole extensometer designed for applications where easy access to the borehole collar is available. It provides a simple and reliable way to monitor ground and rock deformation in geotechnical and underground projects.
This mechanical extensometer is suitable for 50 mm diameter boreholes and is ideal for use in tunnels, powerhouses, mines, slopes, and deep excavations. The instrument includes a mechanical displacement measuring system, with readings taken manually, offering a robust and low-maintenance solution for field monitoring.
