This paper purports to describe the construction and experimental results of a new surface tester with a stylus. The trial device consits of a sensor, a work table, a gear train, a servomotor, a binarycode drum, electric digital circuits, a code panel, and a recorder. Measured value of surface roughness is held on the code panel and after converted to voltage, it is given as a cuve recorded on a chart paper. The sensor touching periodically the surface of a test piece is an electric contact switch with a stylus driven by an on-off servomechanism. The sensor has a sensitivity of 0.1 micron of roughness height and a low measuring force of about 4 milligrams. It is also shown that this tester gives an accuracy of±0.2 micron.
