2.4 Optional accessories
2.4.1 Measurement platform

Use the measurement platform to easily adjust the position between the instrument and the workpiece to be measured. This ensures a more flexible and stable operation and creates a bigger use scope and measures the roughness on the surface of complex shape parts. When the platform is used the needle position can be adjusted more precisely and it measures more smoothly. It is suggested to use the platform when the Ra value is expected to be small.

2.4.2 Extension bar
Use the extension bar to increase the sensor depth of the workpiece inside. The length of the extension bar is 50 mm.

System description

The roughness tester is suitable for laboratories and the production field. It is able to measure a variety of surface roughness of machined parts. Furthermore, it can calculate the corresponding parameters according to the selected measurement conditions and in addition to that, the measurement results are clearly shown on the OLED display as tables and graphics.
