Parallel testing allows you to test multiple applications or subcomponents of one application to reduce the time. These tests consist of two or more parts that check different components or practical characteristics of an application.
Any machined component has a surface geometry which consists of three basic elements:
● Form or Curvature – whether the surface has irregular bumps or dimensional changes
● Waviness –that depends of the surface that has regular repetitive ripples or patterns
● Roughness – shapes or the irregularities that are smaller than and form part of the waviness pattern
Waviness and roughness are traditionally the most difficult elements to measure when comparing surface finish, however, they have a radical effect on the performance of the finished component. Variations will cause aesthetic appearance changes, component wear variations, oil retention variation etc. Many manufacturers therefore specify a range of roughness values which their components should be manufactured to, often expressed as: Ra, Rq (RMS), RzDIN, Ry, Sm,mm.

We offer:
● Parallel Testers
● Hardness Tester – works by accelerating the internal bounce module against the tested item. Depending on object hardness the kinetic energy of the module is absorbed. Speed reduction is measured and converted to hardness values
● Surface Finish Tester – it is invaluable for tactile and visual inspection of machined component finish
