Inclinometer Access Tubes and Accessories – Model EAN-AT Series
The EAN-AT series of inclinometer access tubes provide a stable and durable guide path for in-place and portable inclinometers used to monitor lateral ground and structural movements.
These self-aligning ABS casings are designed with precision keyways at 90° intervals to ensure accurate and repeatable probe orientation.
The inclinometer casings can be:
-
Installed vertically or inclined in a borehole,
-
Embedded in fill or concrete during construction, or
-
Mounted on structural surfaces such as retaining walls or tunnel linings.
Each standard tube is 3 m (≈9.85 ft) in length, with fixed or telescopic couplings that ensure watertight connections. Joints are secured with pop rivets and sealed with mastic and BOPP tape, maintaining long-term protection against groundwater ingress and deformation.
