KR220 Portable Surface Roughness Tester
Check surface finish where the work happens. The KR220 brings 20 roughness parameters, a clear OLED waveform display and on-device data storage into a compact handheld instrument. Use it to review a machined surface, compare readings and keep measurements ready for later reference.
Why choose the KR220?
- See the surface profile: the 128 × 64 OLED screen shows measurement values and a visual waveform.
- Measure what matters: supports 20 roughness parameters, including Ra, Rz, Rq and Rt.
- Keep a record: stores up to 100 groups of readings, with a real-time clock for data recording.
- Work without a nearby outlet: rechargeable lithium battery provides more than 20 hours of continuous operation, according to the listed specification.
