Crack Width Measuring Camera

The crack width camera combines smart crack detection and measurement with a close focus camera to immediately measure and document crack widths in a construction project.

The most critical criteria for long term durability of a concrete structure is sufficient concrete cover with no defects. Cracking in cover concrete provides a direct path for faster ingress of chlorides and carbonation and a maximum crack width is a common specification requirement.

Crack mapping of complete structures is slow and has issues with traceability. The use of a data logging camera to record crack widths combines measurement with recording and improves the ergonomics of crack mapping on site. 

Applications

The Crack Width Measuring Camera is suitable for the measurement of crack widths between 0.02 and 6.5 mm.

It can be used onsite to record crack width measurements and to take measurements in hard to reach areas with an extension arm. 

Features

The probe hold a CMOS camera with 60 x magnification.

In Accurate Mode the unit measures the precise width of a crack centred in the display perpendicular to the scale. Scale mode takes the same measurement but also highlights the extent of the crack in green. 

In intelligent mode the software determines an average measurement over several points of a crack visible in the display, with a visual indication of each measurement and the average displayed.

The unit is supplied complete with a camera probe, extension arm with flexible coupling and a clear bright LCD screen controller.
