Roughness testers, also called profilometers or surface finish gauges, are precision instruments designed to measure the surface’s roughness or texture. These engineering test and measurement devices quantify the fine irregularities and imperfections of a surface, providing a numerical value for its roughness. A surface roughness tester is significant in ensuring the products meet the specific regulatory standards and determining the surface suitability for desired applications. Our Mitutoyo profilometers provide accurate and reliable surface roughness measurements across various settings.
How Does a Surface Roughness Tester Work?
Surface roughness meters work by moving their built-in stylus (probe) across the surface and measuring the variations in height. These variations are then processed to calculate various roughness parameters, such as Ra (average roughness), Rz (maximum height of the profile), and others, providing a comprehensive analysis of the surface texture.
Why Buy Surface Roughness Meters?
By investing in these surface finish gauges, businesses can detect flaws early, reduce maintenance costs, and achieve superior finishes that enhance the durability and functionality of their products. These testers are a cost-effective option for identifying surface defects, predicting wear and tear, and ensuring the proper fit and function of components.
Check Our Range of Roughness Testers:
We offer quality roughness testers to meet diverse application needs. Our collection includes:
- Skidded Roughness Testers – These testers feature a reference probe (skid or datum) that glides across the surface being measured. They are generally more portable and suitable for on-site measurements. A skidded roughness tester is an economical option for less sensitive surfaces in various industries.
- Skidless Roughness Testers – A Skidless roughness tester is a precision instrument designed to provide accurate measurements where even minor imperfections could compromise performance. It uses a stylus itself as the reference for delicate components.
View Our Quality Roughness Tester Accessories:
Enhance the functionality and versatility of your roughness tester with our high-quality accessories, such as:
- Column Stands – Column stands provide stable and adjustable platforms for roughness meters. They minimise vibrations caused by handheld movement and ensure the tester's consistent positioning.
- Height Gauge Adapters – A height gauge adapter allows the profilometer to be mounted on a height gauge. It enables compatibility between roughness meters and height gauges for increased measurement flexibility and the ability to measure surface roughness at specific heights.
- Standard Stylus – The standard stylus is the key component of roughness testers. It is designed to trace surface contours and provides reliable data for common testing needs.
- Small Hole Detectors – As the name indicates, a small hole detector enables roughness measurement within small holes or confined areas, expanding the application range of the tester.
- Detectors for Soft Materials – A detector for soft materials is a specialised detector designed to measure the roughness of delicate or easily deformable materials without causing damage.
- Deep Groove Detectors – These detectors facilitate roughness measurement within deep grooves or channels, providing access to difficult-to-reach surfaces.
