This model is has a Standard type Drive unit with 4mN detector measuring force. The Mitutoyo SJ-210 Series 178, 178-561-02A Portable Surface Roughness tester combines high accuracy and measurement speed with numerous innovative features creating a new class leader in surface inspection.
Highly versatile and delivers accurate measurements at high speeds, this surface roughness tester is full of features and capabilities that enhance productivity.
Features
Extensive display features that assist measurement
Advanced data storage capabilities
Up to 10 measurement conditions can be stored in the internal memory. Conditions can be quickly read according to the workpiece.
Stylus alarm function
An alarm warns you when the cumulative measurement distance exceeds a preset limit. This feature can be used to prevent problems that would be caused by worn out styli. Any value can be specified as the limit.
Easy setting
Displayed settings can be easily changed by pressing the left and right arrow keys under the sliding cover. For example, these keys can be used to switch the cut-off value (λc) and the number of sampling lengths (N) on the measurement screen.
Setting parameters and recalculating results
The required parameters can be selected from the screen. The sub-menu also lets you specify detailed settings such as the tolerance. After completing measurement, the parameters can be changed and calculation can be executed again using the new parameters.
