The Geosystems Digital Extensometer is a multi-point borehole extensometer (MPBX) that can have 1 to 6 anchor points. It combines a traditional multi-rod design, modern materials, and digital signal processing to dramatically improve the accuracy and reliability compared to similarly priced alternatives. This high precision digital extensometer comprises up to six variable induction displacement sensors. The hermetically sealed electronics operate indefinitely when submerged in water.

The on-board micro-processer performs digital signal processing and transmits readings directly in real world units (mm and °C). The output can be read by our low cost readout unit, tablet, or data logger; and can be wirelessly networked for transmission to Cloud based servers.
