Surftest SJ-410 Series 178-Portable Surface

Revolutionary New Portable Surface Roughness Testers Make Their Debut 

Long-awaited performance and functionality are here: compact design, skidless and high-accuracy roughness measurements, multi-functionality and ease of operation.

SJ-400 Series Performs Skidless Measurements 

The height/tilt adjustment unit comes as standard for leveling the drive unit prior to making skidless measurements and, supported by guidance from the unique DAT function, makes it easy to achieve highly accurate alignment. 

More Measuring Functions Than Expected From a Compact Tester 

Wide Choice of Evaluation Possibilities with Analyzing Program FORMTRACEPAK V5 

The new SJ-411/412 has numerous innovative features combined with high accuracy and a competitive price makes this instrument the new leader in its class. 

  • Both skidded and skidless measurement are possible with this series. Equipped with 46 roughness parameters that conform to the latest ISO, DIN, ANSI, and JIS standards.
  • A wide-range, high-resolution detector and a drive unit provide superior high accuracy measurement in its class. Detector
