Tips: What is a surface roughness tester?

A surface roughness tester is an instrument used to measure the texture, finish or roughness of a surface. It is a precision instrument used in various industries such as manufacturing, engineering, and metalworking. The device typically measures the height variations on a surface, such as the peaks and valleys, and provides a numerical value that quantifies the roughness of the surface.

Surface roughness testers are typically portable and easy to use. They consist of a stylus or probe that is moved across the surface to be measured. The stylus is connected to a sensor that records the surface's topography, and the instrument generates a numerical value that represents the surface roughness. The result can be displayed on a screen or printed out.

Surface roughness testers can be used to assess the quality of a surface finish or to determine if a surface meets specified standards. They are commonly used in applications such as quality control, inspection, and research and development.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
