RobertsonGeo - Elastmeter
Well Logging System
    Model: Elastmeter
    Country of Origiin: UK
    Use: The Elastmeter is a borehole lateral load tester designed to figure out deformation characteristics of the ground ranging from soft rock to hard rock. The deformation characteristics become useful information especially for the construction of large scale structures such as dams, bridges and high-rise buildings.

The Elastmeter has a range of probes to provide pressuremeter tests of rock in BQ (60 mm), NQ (76 mm) and HQ (98 mm) boreholes. Both pressure and displacement are measured directly in the probe using electrical transducers. A mechanical arm is used for the measurement of displacement making maintenance easier. Applied pressure is measured by a precise semi-conductor transducer in the probe.

Pressuremeter and data recorder:
The system comes complete with data recorder, probe and cables for up to 200m use.
