Description
Overview
The GAOTek Surface Roughness Testing Instrument is a high-precision surface roughness tester. It uses an inductive sensor to measure roughness parameters Ra, Rz, and Rq on various surfaces, including plane, bevel, cylindrical, curved surfaces, small holes, grooves, and axles. The device features a 4-digit LCD with blue backlight, USB and Bluetooth data output, and can store up to 100 groups of data. It’s lightweight and portable, making it ideal for on-site inspections of large workpieces and production lines. This tester is a valuable tool for quality control in manufacturing, machining, and testing departments.
