Mitutoyo SJ-412 Offers
Providing both skidded and skidless measurements, this roughness tester has 46 roughness parameters that conform to ISO, DIN, ANSI, and JIS standards. Work with confidence with its high-resolution detector providing accurate measurements and features a high level of quality control. In addition, this roughness tester works with a digital filter function that delivers non-distorted roughness profiles and a limited contour analysis function that supports; step, level change, area, and coordinate difference measurements.
