KR230 Surface Roughness Tester
KR230 Surface Roughness Tester
This surface roughness tester is a handheld instrument suitable for the on-site and mobile measurement, can measure a variety of machined parts, evaluating surface textures with a variety of parameters accord to various international standard. The measurement results and roughness curves showing digital/graphically on the color display. This roughness instrument adds more function: windows menu, the display type can be changed for easy operation for both left, right hander, upper and lower limit alarm can be set. You can also delete one history measurement or all of them.
Surface Roughness Tester KR230, the display will automatically shift the range during measuring process, you can see dynamic roughness curve, and roughness value number.

Probe Leveling
22mm adjustable support
Surface roughness tester, for flat surface, when the testing surface is small for the compete device to place it on, a suitable height adaptor should be used.
The surface roughness tester KR230 standard package include a small height adaptor, height adjustable is around 22mm, in this situation to place the front part of the main unit on the testing surface to avoid much probe pressure is very important.
Optional Platform for Surface Roughness Tester KA520
The surface roughness tester has optional sensors for wide application: in grooves, for curves, very deep grooves etc. these measuring need a height stand.
When the roughness tester is measuring groove, curved, the main unit are not allowed to get to the workpiece, for this KR230 surface roughness tester, we recommend optional platform KA520 - metal platform, or KA620-marble platform. KA520 is around 6kg, it is economical for transportation by DHL, FedEx, and this KA520 now is have been upgraded, it is now as firm and flexible as KA620.
