The Mechanical Triaxial Jointmeter is designed to monitor three way displacement (X, Y and Z) across joints or cracks between adjoining concrete and rock structures. The Jointmeter comprises two elements; a zinc coated measurement arm and a Stainless Steel reference head, both attached to reinforcing bar embedment anchor stems.  The measurement arm incorporates three orthogonal locating bushes, designed to receive a mechanical or electronic micrometer.
The Stainless Steel reference head is a cubic anvil, with precision machined reference faces, providing a surface against which the triaxial displacement measurements are made. Manual measurement with a mechanical gauge is a more preferred option when fewer readings are required.
