The DIACHECK-CT series digital arc gauge enables bend inspection on tube bending machines and the direct, instant reading of internal or external radii or diameters in a range from 100 to 10000 mm.
Bend inspection on tube and profile bending machines is a common industrial application.
The high-precision arc gauge in the DIACHECK-CT series is designed to measure the radius of curved objects such as tubes, profiles and rolled sections quickly and precisely.
The arc gauge allows measurement of the radius of curvature or of the internal or external diameter of a given part using the three-point circumference measurement method.
The DIACHECK-CT is a practical, precise and, above all, easy-to-use digital instrument. Simply place the arch gauge on the surface of the object to be measured and the radius of curvature immediately appears on the display.
Accurate bend measurement is essential on any tube or profile bending machine. Investing in a reliable arc gauge can help you get the most out of the bending operation, ensuring that all bends are precise and comply with the required specifications. Arc gauges measure the arc length from one end of the bend to the other, enabling extremely precise measurements compared with manual methods.

In depth
Arch gauges are an indispensable instrument for measuring objects with curved geometry such as tubes, sheet metal, glass and profiles. Their technology makes it possible to calculate the curvature of such materials with extreme precision.
Using these instruments, professionals and enthusiasts in fields such as mechanical engineering, steelwork, joinery, glass production and furnishing elements can create objects and parts with perfectly calibrated, uniform curves, guaranteeing a high-quality end result.
Arch gauges make it possible to determine the precise curvature of every single tube or profile, avoiding problems during positioning and installation.
Sheet metal and glass also require particular curvature, especially in architecture and in the furniture industry.
Arch gauges allow curvature to be measured precisely and uniformly, avoiding the risk of chipping or breaking the material during processing and positioning.
These instruments also make it possible to calibrate the curvature of sheet metal and glass perfectly, guaranteeing an end result that is both attractive and functional.
Lastly, arch gauges are widely used in the metalworking industry for bending metal profiles. They allow the most accurate possible measurement, avoiding errors that could compromise the stability and functionality of the products made.
What is more, the measurements taken with arch gauges make it possible to guarantee uniform curvature throughout production, assuring customers of an excellent end result.
