Inclinometer casing is a special grooved tube, generally installed in a borehole, used in conjunction with inclinometer systems to monitor horizontal soil movements. Flush-coupled inclinometer casing is a special ABS grooved tube, machined at the end to have a self-aligning junction. It is produced from high-quality virgin ABS plastic.
During manufacturing particular attention is paid to minimise the spiral of the casing grooves and to machine the aligning key for casing junction with self-aligning couplings. Casing sections are assembled by means of couplings glued together, riveted and sealed with mastic and tape.
