A digital concrete crack width meter is a precision measuring tool specifically designed to measure the width and changes of cracks on the surface of building structures, bridges, tunnels, or concrete components. It helps engineers and inspectors monitor crack development trends, assess structural safety and durability, and promptly identify potential risks. Depending on the measurement method, crack width measuring instruments can be categorized as manual scale type, optical type, electronic type, or non-contact laser measurement type.

How does a digital crack monitor work?

The working principle of a crack width measuring instrument is typically based on precise measurement of length or displacement. Manual scale types directly read the crack width using a ruler or vernier; optical or electronic types measure the distance between the two sides of the crack using a microscope, camera, or laser scanning, and convert the data into a width value; non-contact laser instruments obtain the distance between the two sides of the crack through laser projection and reflection, achieving high-precision measurement and dynamic monitoring. Some advanced instruments can also automatically record and save measurement data, facilitating long-term tracking of crack changes.

How to choose a suitable digital concrete crack gauge?

When choosing a digital crack gauge monitor, the selection should be based on measurement accuracy, measurement range, operating environment, and application scenario. For large structures such as bridges and tunnels, high-precision electronic or laser instruments that support data logging and remote monitoring should be given priority. For general building or concrete structure testing, manual calibration or optical instruments are sufficient. In addition, the durability, portability, accessory support, and compliance with relevant engineering standards (such as GB, JGJ, etc.) of the digital crack gauge monitor should also be considered to ensure reliable measurement results and ease of long-term use.
