Front Loading Oedometer

The oedometer consolidation test determines the rate and magnitude of consolidation of a soil specimen restrained laterally and subjected to a number of successive vertical load increments.

The oedometer apparatus has a rigid aluminium alloy frame which avoids distortion under load. The lever arm assembly is supported in precision self- aligning bearings. Consolidation cells, dial gauge/displacement transducer, weight sets and bench are not included and have to be ordered separately (see Accessories).
