Mitutoyo Surftest SJ-410 Portable Surface Roughness Tester
The Surftest SJ-410 surface roughness measuring instrument offers numerous innovative features to provide smoother operation and more accurate measurements in an easy-to-use, portable unit with a high straightness specification of 0.3 – 0.5μm over a traverse length of 25 – 50mm. The Surftest SJ-410 surface roughness measuring instrument provides both skidded and skidless measurements. The SJ-410 surface roughness measuring instrument is equipped with 46 roughness parameters that conform to the latest ISO, DIN, ANSI and JIS standards. The unit’s high-resolution detector and drive unit provide a wide range of highly accurate measurements and ultra-fine steps. Using the unit’s skidless measurement and curved compensation functions, straightness, waviness and evaluation of cylinder surface roughness can be easily measured and evaluated.
A wide-range, high-resolution detector and a very accurate drive unit provide superior high-accuracy measurement in its class:
