Consolidation cells' accessories

This accessory, avalibale for all consolidation cell models, shoul be ordered separately.

Calibration disc for consolidation cell
Description

 

Oedometer consolidation test accessories

Main Features

The oedometer consolidation test requires correction for apparatus flexibility. 

For this reason, consolidation cell assemblied with a hard steel calibration disc should be used to estimate this correction to be applied to the measured vertical deformation.

This accessory, avalibale for all consolidation cell models, shoul be ordered separately.

Upper and lower porous stones along with cutting ring, already inclueded in each consolidation cell, can be ordered as spare parts.
