This has been especially manufactured to measure crack widths in concrete. Consisting of a high definition
Microscope connected to an adjustable light source which provides a well-illuminated image under all working
The image is focused by turning the knob on the side of the microscope and the eyepiece graticule can be rotated through 360 degrees to align with the direction of the crack being examined.
The 4mm measurement has a lower scale divided into 0.2mm divisions. Relevant Standards (BS 8110 part 2) state eg: the maximum crack widths should not exceed 0.3mm which is 15 divisions on the scale for most types of environment.
