Professional Surface Roughness Tester
The TIME3100 Surface Roughness Tester is a professional surface roughness tester designed for fast, accurate, and portable measurement of surface finish in manufacturing, machining, quality control, and laboratory applications. Compact enough to fit in a pocket while delivering reliable measurement performance, the TIME3100 is an ideal solution for evaluating the surface roughness of machined parts, precision components, shafts, bearings, moulds, and fabricated metal surfaces. Complying with ISO and DIN standards, the instrument provides dependable roughness measurements for production inspection and quality assurance.
The TIME3100 Surface Roughness Tester measures the two most widely used surface roughness parameters, Ra and Rz, across a measuring range of Ra 0.05–6.5 μm and Rz 0.1–50 μm. Furthermore, the instrument is suitable for measuring flat surfaces, external cylindrical surfaces, and inclined workpieces, providing excellent flexibility across a wide range of industrial applications. The precision piezoelectric pickup and diamond stylus ensure stable measurement performance and repeatable results throughout daily operation.
Designed for Industrial Surface Finish Inspection
The TIME3100 features dual OLED dot matrix displays positioned on both the front panel and the top cover, allowing operators to conveniently view measurement results from different working positions. In addition, all calculated roughness values are displayed immediately after each measurement, improving inspection efficiency on production lines and in workshop environments.
The TIME3100 Surface Roughness Tester incorporates enhanced sensor protection for improved long-term reliability while maintaining high measurement accuracy. Moreover, low battery indication, over-limit alarms, and system fault warnings provide dependable operation during daily inspections. Powered by a rechargeable lithium-ion battery with approximately three hours of charging time, the TIME3100 offers a practical and portable solution for professional surface roughness measurement.
