Product type
A surface roughness tester is a precision instrument used to measure the texture of a surface. It works by moving a stylus across the surface and recording the vertical deviations of the surface profile. This data is then analyzed to provide a roughness value, which indicates the quality and finish of the surface. Surface roughness testers are commonly made from durable materials such as aluminum or plastic and often feature electronic components for data processing.
| Measurement Range | 0.01 to 10 µm |
| Accuracy | ± 10% of reading |
| Roughness Parameters | Ra, Rz, Rq, Rt |
| Power Source | Battery or AC power |
| Display Type | Digital LCD |
| Data Output | USB or Bluetooth connectivity |
When choosing a surface roughness tester, consider the measurement range and the types of roughness parameters you need to assess, such as Ra or Rz. It is also important to evaluate the accuracy and resolution of the device for your specific applications. Additionally, check for connectivity options for data transfer and ensure the device is compatible with your existing systems. Specify the quantity required and any specific features or certifications that may be necessary for your industry.
