Inclinometer Casing overview

Accurate ground movement monitoring starts with a reliable foundation. RST Instruments' Inclinometer Casing provides a precision-guided access tube for measuring lateral displacement within soil and rock. 

Designed for short- and long-term monitoring, it supports inclinometer probe surveys and digital in-place inclinometer systems across a range of geotechnical projects.

With high-accuracy, machined guide grooves, durable ABS construction, and secure coupling options, RST Inclinometer Casing helps deliver consistent measurements and dependable performance in demanding field conditions.

From slope stability to critical infrastructure monitoring, it gives engineers the foundation they need to understand subsurface movement and assess changing ground conditions.

Built for precision and demanding conditions

RST Instruments' Inclinometer Casing is engineered to support accurate measurements from installation through ongoing monitoring. Installed in boreholes, embankments, piles, or concrete structures, the casing guides an inclinometer probe along two orthogonal measurement axes. The carefully machined grooves maintain probe orientation, ensuring reliable readings and reducing errors that arise from casing twist.

Manufactured from virgin ABS resin, the casing offers flexibility, impact resistance at low temperatures, and durability for challenging site environments. Self-aligning couplings provide secure connections designed to resist water and grout ingress.

Available in 70 mm and 85 mm outside diameters, with standard section lengths of 1.5 m and 3.5 m, RST Inclinometer Casing can be adapted to meet a variety of installation requirements.

Why choose Inclinometer Casing?

Inclinometer Casing for geotechnical and infrastructure monitoring

Subsurface movement can reveal major changes in ground and structural behaviour. Inclinometer Casing provides the access required to measure these changes and support informed engineering decisions.
