Surface roughness tester

In the industry, multiple methods are used to achieve the desired smoothness and roughness in surface processing. For successful work, a precise roughness measuring device is important to be able to extract the correct values in every situation, depending on the industry and project.

Standardized and precise roughness measuring devices from SaluTron®

According to international standards, our measurement technology determines the following parameters:

• Ra (Average Roughness): This characteristic is based on the arithmetic mean of all heights. It represents the average deviation of the profile from the mean line.
• Rq (Root Mean Square Roughness): This parameter is calculated by taking the mean of all squared deviations.
• Rz (Mean Roughness Depth, also known as ten-point height): The roughness measuring device measures the height of the highest profile peak and the lowest depth, and calculates the value from the sum within a single measurement range.
• Rt (Maximum Roughness Depth): Within the total distance, Rt represents the value from the lowest point to the highest peak.

The measurement of smoothness and roughness of surfaces contributes significantly to cost reduction and ensures product and material quality. The applications range across various industries, such as material manufacturing, automotive industry, packaging and construction industry, laboratories, and mechanical engineering. We also offer roughness measuring devices in different qualities and price ranges for your private projects.

We offer the following roughness measuring devices in our range:

• SRT 5000
• SRT Pro
• TR-110/TIME3110
• TR-200/TIME3200 / TR-220/TIME3202
• R 130/R 135

Our models measure using the stylus method. A diamond tip moves at a constant speed over the surface to be measured and captures the stylus profile from the vertical surface. This allows for the determination of various roughness parameters. Each measuring device meets the necessary DIN standards to ensure flawless operation. Upon request, we are happy to provide all devices with an additional test report.
