Description
Overview
The GAOTek Portable Surface Roughness Tester is a portable surface roughness tester that offers high precision and versatility. It uses an inductive sensor to measure roughness parameters on various surfaces, including flat, cylindrical, curved, and even small holes and grooves. 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 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. It comes with a 12-month warranty.
