The Encardio-rite model EDS-64U/D single position mechanical borehole extensometer is suitable for 50 mm upward, downward or inclined boreholes. It is a precision mechanical instrument designed to help civil engineers and geologists in the measurement of deformation of rock mass and adjacent or surrounding soil.
Together with anchor bolt load cell and tape extensometer, it is essential equipment for investigation and monitoring of foundations, slopes & embankments and for studying the behavior of rock around underground cavities, tunnels and mines. The borehole extensometer is an important instrument especially in investigation of underground cavities and landslides.
