Surface Roughness Tester
The split TYPE roughness tester is a high-precision surface roughness testing instrument that measures for roughness of a variety of machined parts, including flat surfaces, inclined surfaces, outer cylindrical surfaces, curved surfaces, small holes, grooves etc.
The surface roughness tester is for metal and non-metal parts:especially suit for machined parts in machining manufacturing. It is usually used for measuring roughness for small work piece, as well as for on-site inspection of large work pieces, this surface roughness tester is an ideal instrument for testing, quality inspection, outgoing inspections by other departments, the measurement will not cause damage to the work piece.
