Rod Extensometer Single and Double Point
The Single Point Rod Extensometer is an inexpensive, simple, rugged, and reliable device to monitor deformation in under ground workings. The Double Point Extensometer incorporates the use of two points which allows the engineer to distinguish between dangerous deep seated movements and more trivial surficial spalling.
