Key Performance Features
-
Advanced Measurement Capabilities:
The SJ-220 is capable of measuring up to 39 surface roughness parameters, including commonly used metrics such as Ra, Rq, Rz, and Rt, making it suitable for a wide range of surface types and tolerance specifications. -
Standards Compliance:
Fully compliant with ISO 1997, JIS 2001/1994, ANSI, and VDA surface texture standards, the SJ-220 supports global manufacturing protocols and ensures traceable, standards-based reporting. -
Intuitive Dual Interface:
Equipped with a 2.8-inch full-colour touchscreen and physical control buttons, the device enables flexible operation in virtually any environment, including situations where gloves are required or ambient conditions are less than ideal. -
Drive Unit Options for Application Flexibility:
Choose the drive unit that fits your workflow:-
Standard (SJ-220) – for general-purpose measurements across flat and gently contoured surfaces.
-
Retractable (R-Drive) – retracts the stylus post-measurement to prevent damage in constrained areas.
-
Transverse (S-Drive) – ideal for measuring surface profiles on narrow, recessed, or lateral orientations.
-
Connectivity & Data Management
