GOYOJO Surface Roughness Gauge 0.01μm Tester with OLED Display

Description

Product Overview

The GOYOJO Surface Roughness Gauge is engineered for professionals who demand exacting surface texture data. Featuring a 0.01μm indication accuracy, the instrument measures Ra, Rz, Rq and Rt across a broad range—0.05‑15.0μm for Ra and Rq, 0.1‑50.0μm for Rz and Rt. A high‑speed DSP processor accelerates data acquisition and calculation, delivering results in real time. The wide‑temperature OLED display remains bright in harsh workshop lighting, while the compact form factor (2.76 x 0.94 x 4.06 in, 7.04 oz) ensures portability. Power is supplied by a built‑in lithium‑polymer battery with a USB‑C charger, providing up to 10 hours of continuous operation.

Usage

This gauge excels in diverse environments—from automotive assembly lines and aerospace component inspection to electronics manufacturing and medical device research. Its adaptable probe accommodates flat, ex‑circle, conical and grooved surfaces, even those exceeding 80 × 30 mm. Engineers can quickly assess tool wear, verify machining tolerances, or validate surface treatments without removing parts from the production line. The intuitive interface and single‑button operation reduce training time, allowing technicians and quality‑control staff to obtain reliable data on the shop floor or in a laboratory setting.
