Split Type surface Roughness Meter NDT160 high-precision roughness Tester measuring instrument
Split type roughness meter NDT160
The split type roughness meter NDT160 is a high-precision surface roughness measuring instrument that can measure the roughness of various machined parts, including planes, bevels, outer cylinders, curved surfaces, small holes, grooves and axles. .
Scope of application: Surface roughness measurement of metal and non-metal tested parts, applicable to a variety of machined parts, machining manufacturing, testing, commodity inspection and other departments, especially for on-site inspection of large workpieces and production lines, as well as testing, Excessive verification by departments such as metrology and commodity inspection will not cause damage to the workpiece.
