A high quality microscope designed for measuring crack widths in concrete members, masonry walls and other structures. The apparatus operates by an adjustable lamp unit and the image is focused by turning a knob. The eyepiece scale can be turned through 360° to align with the direction of the crack or pitch under examination.
Used for determining the deflection of bridges, ceilings or any suspended structure.

Used to determinate the in-situ stress, deformability and resistance feature of masonry.
Introduction
The in-situ stress, deformability and resistance feature of masonry can be determined by the flat jack method . The test is performed by making a cut to a uniform depth into the mortar courses and inserting the flat jack or couple of jacks, which are pressurized to the desired level.
Test modes:
For stress determination a single flat jack has to be used.
For deformability and resistance determination two flat jacks have to be used.
The flat jacks have to be pressurized and the strain measured using the Analog or Digital mode as follows:
Analog measurement
The following accessories have to be used:
Digital measurement
The following accessories have to be used:
Note. In order to fill conveniently the testing cut, use the sets of steel sheets of the same flat jack dimensions. See accessories.
