Leeb410 is a professional portable surface roughness testing instrument manufactured by Chongqing Leeb Instrument. Adopting advanced high-speed DSP processing technology and high-precision inductive sensor, this tester delivers fast, stable and accurate surface roughness measurement results.
It can accurately detect the surface roughness of flat, curved, cylindrical, grooved and small-hole workpieces, widely applicable to machined parts, molds, auto parts and precision components. Supporting Ra, Rz, Rq, Rt multi-parameter testing and GAUSS filter processing, it fully meets ISO, DIN, ANSI and JIS international industrial testing standards. Multiple optional sampling lengths adapt to different material and processing requirements.
Featured with high-definition OLED display, the device ensures clear data viewing in various light conditions. The tolerance alarm function helps operators quickly screen unqualified products and improve detection efficiency. Lightweight portable structure and rechargeable lithium battery design support long-term on-site workshop and field detection. With stable performance, low error rate and simple operation, Leeb410 is an ideal surface finish inspection equipment for industrial quality control and laboratory routine testing.
Leeb410 surface roughness tester features ultra-high resolution of 0.001μm. The measuring range is Ra 0.05-10.0μm and Rz 0.1-50μm. It supports three optional cutoff lengths of 0.25mm, 0.8mm and 2.5mm, with 6mm effective tracing length. The indication error is ≤±10% and variation is less than 3%, ensuring stable and repeatable testing results. It adopts piezocrystal inductive sensor and built-in GAUSS filter, supporting multi-parameter synchronous testing. Powered by 3.7V rechargeable lithium battery, it features low power consumption and long standby time.
