Mahr Federal will feature its new Pocket Surf PS1 portable surface finish gage at the EASTEC 2007 Exposition. Based on Mahr Federal’s Pocket Surf portable surface finish gages, the new Pocket Surf PS1 weighs 14 oz and can measure more than 24 surface finish parameters with its high resolution inductive probe. The PS1 offers a host of new features, including memory, USB connectivity, optional PC software, and a large measuring range. The unit’s large display provides measurement data at a glance and displays all functions in plain text. The most frequently used parameters--Ra and Rz--are directly selectable with more than 22 others easily accessible with scrolling function keys. Cutoff lengths are freely selectable and an integrated calibration master eliminates the need for external calibration. A large measuring range of up to 350 microns allows versatility of application, including the ability to measure very rough surfaces.The drive unit can be rotated as well as moved longitudinally; and the PS1 can measure upside down, mounted on a surface plate or measuring stand, or even perpendicular to the contact surface with an optional end face vee-block. A wide range of available pick-ups add flexibility. For example, one pick-up can be used to measure inside bores with diameters as small as 3 mm. A dual-skid pick-up can be used for sheet metal and roller surface measurements; another is designed for concave and convex surfaces; and still others for measurements at such difficult to reach points as deep in grooves. According to Mahr’s press releaese, this is the first instrument of its kind to include a USB interface. Therefore, the Pocket Surf PS1 can be connected to a PC for transfer and storage of data without requiring the installation of any additional software or drivers. An optional software package is available for viewing profiles and results on a PC. This powerful functionality makes it possible to collect large amounts of measurement data with the handheld device and transfer this data later to archival systems for quality system documentation requirements.
