Professional Surface Roughness Tester
The TIME3221 Surface Roughness Tester is a professional surface roughness tester designed for advanced surface finish measurement, profile analysis, and precision quality control in manufacturing, machining, research, and laboratory environments. Featuring a separated drive unit, touchscreen TFT display, comprehensive roughness parameter analysis, and high-accuracy inductive pickup, the TIME3221 delivers laboratory-grade measurement performance while remaining portable for workshop inspections. Complying with ISO 1997 standards and compatible with ANSI and JIS 2001 standards, the TIME3221 is an ideal solution for inspecting precision machined components, automotive parts, aerospace components, moulds, bearings, gears, and high-performance engineering surfaces.
The TIME3221 Surface Roughness Tester measures an extensive range of roughness and waviness parameters, including Ra, Rz, Rq, Rt, Rp, Rv, Rsk, Rku, Rc, Rpc, RSm, Rmr, Rk, Rpk, Rvk, Mr1, Mr2, A1, A2, together with numerous primary profile (P) parameters. Furthermore, the high-precision inductive pickup with an optional 5 μm or 2 μm diamond stylus delivers outstanding repeatability and measurement accuracy. Selectable cut-off lengths, evaluation lengths, and advanced 2RC and Gauss digital filters ensure compliance with international surface roughness measurement standards.
Designed for Advanced Surface Finish Analysis
The bright touchscreen TFT LCD clearly displays measurement parameters together with graphical surface profiles, allowing operators to analyse surface texture quickly and accurately. In addition, the compact separated drive unit provides greater flexibility when inspecting difficult-to-access workpieces, improving measurement convenience across a wide range of industrial applications.
The TIME3221 Surface Roughness Tester supports both USB and RS232 communication for seamless integration with computers and quality management systems. Moreover, optional printer connectivity enables direct printing of measurement parameters and graphical profiles for inspection reports. Powered by a rechargeable lithium battery, the TIME3221 combines advanced measurement capability, portability, and professional analysis tools, making it an ideal surface roughness tester for precision manufacturing and laboratory-quality inspection.
