The DIACHECK-CT series digital radius and diameter gauge provides direct, instantaneous readings of internal or external radii or of diameters in a range from 100 to 10000 mm.
The high-precision digital radius and diameter gauge of the DIACHECK-CT series is designed to measure the radius of curved objects such as profiles, calenders, supports, doors and guards quickly and precisely.
This measuring instrument enables measurement of the radius of curvature or of the internal or external diameter of a given part using the three-point circumference measurement method.
DIACHECK-CT is widely used in the wood bending sector and in the production of furniture elements, where determining the mating profile of several parts is very important.

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.
