Roughness Meter Ra Rq Rv Rs Etc 12+ Parameters, Digital Surface Roughness Tester

Product Description

Precise Multi-Parameter Profiling: GOYOJO GSR750 Surface Roughness Gauge, offers the capability to measure Multiple surface roughness parameters, including Ra, Rz, Rq, Rt, Rp, Rv, R3z, R3y, Rz(JIS), Rs, Rsk, Rku, Rsm, and Rmr. This wide range of parameters makes it suitable for various industrial applications.
Diamond Stylus Inductive Sensor: High-precision inductive sensor with a 5 μm diamond-tipped stylus. Robust design and constant 4 mN contact force ensure stable, repeatable readings on metal or coated parts, even on fine features. Advanced RC/PC-RC/Gauss/D-P filters let you adapt measurements to any surface texture.
User-Friendly Operation: Large backlit LCD shows live profile curves and all parameter values. Intuitive menu system, auto-calibration and auto-save ensure error-free results. Ideal for engineers, QC inspectors, and maintenance professionals.
Long-Life Battery & Portability: Internal Li-ion battery provides over 20 hours of continuous use, enabling full-day field or shop-floor inspection without recharging. Compact (156×55×46.5 mm) handheld design and auto-sleep power-saving extend operation time.
Solve Critical Pain Points: Prevent costly rework by detecting roughness deviations early (e.g., bearing failures, gear wear). Replace manual inspections with ASTM-certified precision.
