Surface Roughness Tester Surftest Profilometer with 4 Parameters Ra Rz Rq Rt RS232C Interface

Application: Widely used in production site to measure surface roughness of various machinery-processed parts. Manual or automatic shut down. The tester can be switched off by pressing the Power key at any time. On the other hand, the tester will power itself off about 5 minutes after the last key operation.
