Length Comparator

This apparatus is used to determine the changes in length of cement prisms in the accelerated soundness test and the linear shrinkage of cement mortar. It is also used to measure length changes of 40x40x160 mm, and other sizes of cement and concrete specimens.
The instrument consists of an analogic or digital length gauge, which is mounted on a steel frame. The top anvil is adjustable to suit the required specimen.

Overall dimensions: 180x180x490 mm
