Lightweight and flexible, our SMART MPBX (Multi-Point Borehole eXtensometer) has six anchor points and an integrated electronic readout head for monitoring deformations within the rock mass.

The small instrument diameter means that the head can be recessed in a 50 mm (2 inch) borehole – no need for oversize 
holes or reamed collars. It also allows multiple MPBX’s to be installed within the same borehole – head to toe.

Each instrument is custom manufactured to the length you require, and allowing you to place the anchor locations where you need. 
They arrive on site ready to install. Just place in a borehole and 
grout. No assembly required. Our biggest selling item, the 
SMART MPBX is in use around the world.
