Available upon request: reference standard No. 81.60000 with calibration certificate Surface Roughness Testing Pocket Surf ® Gage The Pocket Surf gage is a pocket-sized, economically priced, completely portable instrument for performing traceable surface roughness measurements on a wide variety of surfaces (including small inside diameters). The Pocket Surf gage is solidly built with a durable cast aluminum housing to provide years of accurate, reliable surface finish gaging. Designed for use in a shop environment or in the laboratory, the Pocket Surf works on both horizontal and vertical surfaces. It can be used at any angle and can even be held upsidedown. For even greater versatility, it operates in four probe positions – closed or with the probe at 90˚, 180˚ or 270˚. Use the Pocket Surf for flat surfaces of both, inside and outside diameters, as well as many difficult-to-gage surfaces. Capabilities The Pocket Surf can measure any one of four switch-selectable parameters. Ra Average Roughness Ry Maximum Roughness Depth Rmax Maximum Roughness Depth (DIN) Rz Mean Roughness Depth (DIN), also called Rtm Rmax and Ry are convenient “burr” and “scratch” control parameters and valuable additions to Ra and Rz. The gage’s digital display is conveniently located on the top of the unit for optimum visibility. The easy-to-read LCD readout presents the measured roughness value, in microinches or micrometers, within half a second after the surface is traversed. Out-of-range (high or low) and “battery low” signals are also displayed. Selectable Traverse Length 1, 3, or 5 cutoffs of .030" (0.8 mm) each, permit checking surface lands as short as .075" (1.9 mm). The start switch is centrally located for optimum stability. 4 possible measuring positions of the stylus 270° 180° 90° closed J-9
J-10 Surface Roughness Testing Pocket Surf Measurement Parameters Ra — Roughness Average The arithmetic average height of roughness irregularities measured from a mean line within the evaluation length (L). Rmax — Maximum Roughness Depth (per DIN) The largest of the 5 maximum peak-to-valley roughness depths in 5 successive sampling lengths. In the illustration below, Rmax (DIN) = Ry 4 Rz — Mean Roughness Depth (per DIN), also known as Rtm The mean of 5 maximum peak-to-valley roughness depths in 5 successive sampling lengths Note: To fully meet the requirements of DIN 4768 for Rmax and Rz, probes having a stylus radius of .0002" (5 µm) are available. Ry — Maximum Roughness Depth For the evaluation length equaling one cutoff, it is the vertical distance between the highest peak and the deepest valley within the sampling length. For the evaluation length equaling 3 cutoffs, it is the largest of the 3 maximum peak-to-valley roughness depths in 3 successive sampling lengths.
