The Quick Joint inclinometer casing is an alternative to the traditional inclinometer tubes, mainly designed for earth-fill and rock-fill dams, and deep borehole applications. Quick Joint tube offers simple and fast installation, consistent joint and deeper tube grooves. O-rings prevent ingress of grout or water. The fitted-at-factory coupling and the alignment keys assure a perfect grooves continuity. Telescopic section and a variety of settlement rings for either borehole and embankment installations permit to combine inclinometer and settlement measurements in one borehole.
