Crack Width Microscope precisely measures cracks in concrete and masonry construction materials. Repeated measurements can be performed at the same spot and recorded on the crack record sheet to monitor changes over time. Exact crack dimensions are quickly determined in one step, and surfaces are not defaced with embedded measuring points or mounting hardware. The objective lens is positioned on the surface over the crack and the knurled knob on the side is used to sharpen the focus. The battery-powered lamp adjusts to provide just the right amount of illumination, and the eyepiece rotates 360° to align the optical measuring grid with the crack.
40X image magnification and measuring range of 4.00mm ensure highly accurate measurements for a wide variety of crack widths. The dual optical scale features coarse divisions of 0.2mm with fine graduations of 0.02mm. Rugged metal housing and sturdy construction stand up to harsh field conditions. Supplied with calibration certification from the UK National Measurement Accreditation Service (NAMAS).
