We are as a distinguished manufacturer and supplier of premium quality Crack Width Microscope. This is made in sync with defined norm of the arena using latest techniques and quality assured raw materials. As a result our offered Crack Width Microscope is widely used for measuring crack widths both in concrete and other materials. The image of this microscope is focused by turning the knob at the side of the microscope and the eyepiece graticule can be rotated through 360 to align with the direction of the crack under examination. The 4mm range of measurement has a lower scale divided into 0.2mm divisions. These 0.2mm divisions are sub - divided into 0.02mm divisions. The instrument is a microscope which has a calibrated graticude (scale). When you focus the instrument on the concrete surface the graticule can be seen through the eyepiece it looks as if the scale is on the crack which allows the user to accurately measure the width of the crack. Current Codes of practice state that calculated maximum crack widths should not exceed certain values: e.g. 0.3 mm in BS 8110: Part 2 for most types of environment. This value of 0.3 mm is 15 divisions on the graticule. Microscope is very easy to use and comes with simple instructions in a wooden carrying box.
