Surface Roughness Tester LSRT-A10 has a measuring range of 640 µm (-320 µm to +320 µm) for Z-axis and 17.5 mm for X-axis. This tester comprises of a main unit and an external drive unit, allowing for more flexible measurements. The main unit features a 3.5-inch color touch LCD that supports both touch and button controls. Also, it features a built-in rechargeable battery that supports over 50 hours of continuous use. Our tester is used for surface roughness measurement for metal and non-metal.
