Hello,
My employer is prepared to spend about $8~10K on a surface roughness tester. Has anyone experience with the SJ-401 by Mitutoyo or the Model 440 (Multiple Parameter Unit) by Precision Devices? Any other recommendations for measuring Ra, Rmax, Rt, Rz?
Our specifications are fairly simple. Ra 1.6, 3.2, Rmax=40; Rmin=25, (microns). Some capability to address porosity, ie. Sk (skewness), would be nice but not absolutely necessary. A skidless model would be preferred.
Unit will get heavy use and should last for many years.
