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.

• Built-in 5.7-inch color graphic, back-lit LCD touch-panel display provides superior readability, easy-of-use and visibility in dark environments
• User interface and auto calibration function provides intuitive and easy-to-use operability
• Digital filter function delivers non-distorted roughness profiles for more accurate results
• Limited contour analysis function supports four types of measurement: step, level change, area and coordinate difference
• Password protection prevents unintended operations and protects instrument settings
• Output measured data to a PC with optional RS-232C or USB cable
• Optional column stand available (178-039) to increase operability
