What it is
How it works
General reference — not yet source-verifiedA surface roughness measuring instrument evaluates fine surface texture by tracing a probe across a workpiece and converting the measured profile into roughness data.
A surface roughness instrument is used as a contact metrology tool, and the probe-driven measurement method suits inspection of machined surfaces after finishing operations.
Where it fits in the process flow
The SJ-220 supports measurement setup and data review at the point of inspection, and the optional wireless unit allows data transfer to a device with the dedicated app installed.[1]
Applications
The SJ-220 is used for surface roughness evaluation in production and inspection settings.[1]
The SJ-220 is used where roughness measurements must align with ISO 21920.[1]
