Mikrosize Roughness Meter: Precision Surface Tester for Industrial & Laboratory Use

The Mikrosize Roughness Meter is a high-precision surface roughness tester manufactured by Mikrosize, a trusted supplier of hardness testers, video measuring machines, microscopes, metallographic equipment, and advanced measuring instruments under the Measuring Testing Instrument product line. This versatile device is designed for both production floor inspections and laboratory applications. With the addition of a measurement platform and a PC, it expands into a full desktop roughness measurement system. It accurately measures surface roughness on various machined parts, including flat surfaces, curved components, small holes, grooves, and other irregular geometries. Based on selected measurement conditions, all parameters and roughness profiles are clearly displayed on the LCD screen, printable, or communicable with a PC. The instrument complies with GB/T 3505-2000 (equivalent to international GPS standards for surface texture).

Measurement Principle

The Mikrosize Roughness Meter operates on the stylus profilometry principle. A sensor with a sharp diamond stylus is placed on the workpiece surface. An internal drive mechanism moves the sensor at constant speed across the surface. The stylus follows microscopic peaks and valleys, causing displacement that modulates the inductance of a coil inside the sensor. A phase-sensitive rectifier converts this into an analog signal proportional to roughness. After amplification and level conversion, the signal enters a data acquisition system. A DSP chip performs digital filtering and parameter calculation. Results and profiles are shown on the LCD, printable, or transferable to a PC.
