Description


The CHOTEST SJ5718 Series Entry level Profilometer & Roughness tester, a versatile and cost-effective profilometer series offering easy conversion between contour and roughness measurement, perfect for everything from bearings and gears to phone housings and battery parts.
The SJ5718-PR model is a comprehensive solution for all your metrology needs. For contour measurement, it offers a Z1 range up to 30mm with high precision and a scanning force of 30mN. For roughness measurement, it excels with a ±400μm range, a super-fine 0.001μm resolution, and repeatability of ≤1nm, ensuring consistent, reliable results for parameters like Ra from 0.1μm to 64μm. Its flexibility and economic price point make it an intelligent choice for precision manufacturing QA.


Key Features


  • Dual-Functionality: Easily convert between contour measurement and dedicated roughness measurement with a single system, maximizing your ROI.

  • Deep Hole Capability: The core gams operating system is specifically suited for challenging roughness measurement in deep holes, expanding your inspection possibilities.

  • Broad Application Range: Confidently measure critical components from gearbox pulleys and bearings to modern battery housings and die-casting parts.

  • High-Precision Roughness: Achieve remarkable resolution down to 0.001μm with minimal 1mN scanning force, protecting delicate surfaces.

  • Sturdy & Stable: Built with a robust frame (115kg) and generous travel ranges (X: 100mm, Z: 300mm) to handle a variety of part sizes.
